Editor’s Corner

o f UTIONARy be

Do you still like to make and keep New Year's Resolutions? I do, and first on my List was to re-design that old TIME DESIGNS logo. Well, I had it done in time for this issue. I feel it is a big improvement to the over-all appearance of the magazine, and a trade mark to be associated with. What do you think?

A few of our advertisers mentioned to me that some of you took advantage of the new pricing, and adopted a Sinclair QL into your home (or business). Good news for you. Starting with this issue, TIME DESIGNS will feature on a regular basis, articles and in- formation for the QL. At one time I had been contemplating a separate publication for the QL, but presently I feel this would be pre- mature. The market is rather small right now and I think our readers would be much better served with an over-all Sinclair publication (we are a close knit bunch who understand each other). I have lined up a couple of QL writers who will be bringing us some neat features. By the way, if you haven't heard, Sinclair is discontinuing their QLUB service to American owners. Instead, they have opted to support other QL-related publications (like TIME DESIGNS).

Another QL publication that you may have received free in the mail recently, is the QL REPORT, published by Curry Computer (PO Box 5607 Glendale, AZ 85312). Rob Curry has announced that early this year they will offer the QL REPORT on a subscription basis. I feel that their newsletter would be worth subscribing to, as they have been "pioneers" in the U.S. QL market...stocking products while we were all still skeptical of seeing the QL's arrival here.

If all of this QL talk has brought a lump to the throat of you T/S users (who have no use for this machine), you have nothing to worry about. By no means will TIME DESIGNS short you of information for your computer. You are the main reason for this magazine. This issue has more T/S stuff than ever before, and even additional pages.

CONTINUED NEXT PAGE

Although I have a QL here in the office (for testing purposes), my 2068 with disc drives practically runs this business.

I have a "special offer" for 2Zx81/TS 1000 users only. I have been wanting to de- vote an entire page to special tips and also short programs/routines that you might. like to share with other users. I will print as many as possible. Would you like to see your info and name in print? Any "takers" on my offer? I hope so, aS a column like this is really needed.

Well, it has been two years now since most of us were orphaned by the Timex Com- puter Corporation. Have you realized that the support for your computer has not de- minished, but has for all practical reasons, improved? Quite an amazing story. One of the big "slicks" should do a feature story on our thriving T/S community.

Thank you Sinclair for still supporting us. Although sometimes we haven't understood you, we are very glad that your still hang- ing in their.

To all Spectrum (16k, 48k, Plus and 128k), QL, 2068, 2x81, TS 1000/1500, and 2X80 users...keep up the good work!

“Your readers may be interested in knowing about the availability of 2 relatively inexpensive full size [dot- matrix] printer. A recent catalog from: DAK INDUSTRIES INC., 8200 Remmet Ave., Canoga Park, CA 91394, contained an ad for the GORILLA/BANANA printer for the relatively Jow cost of $89.90 plus $8.00 for P&H. Admittedly, this printer has certain limitations. It does not provide true descenders for letters with tails, but text is still very readable. In my opinion, to obtain a full 80 col. dot- matrix printer for less than twice the price of the 2040 thermal printer is well worth that error in the letter format...ads for TASPRINT claim it will provide true de- scenders with this printer. The ad [for the printer] did claim it was a close out, and quantities were limited so they may be all gone by now. Compatability with the Cen- tronics I/F and TASKORD Il is demonstrated by the fact that this letter was written using them and printed on my GORILLA/BANANA printer."

Vance J Carpenter Fairport, NY

EDITOR: RMG ENTERPRISES, 1419 1/2 7th St., Onegon Céty, OR 97045, has an EPROM that replaces the one in the GORILLA/ BANANA, and gives you descenders. Price 14 $14.95.

"I'd really appreciate help from TIME DESIGNS or any of its many subscribers on the following T/S 1000 and T/S 2068 problems. 1000: How do you reconcile the ORGANIZER (16k) softwere program with a 64k RAM hardware add-on’ Without upgrading the software to 64k, the 64k hardware is useless!!! 2068: How do you get the YU-FILE software program to print graphics output? VU-FILE is the software equivalent of ORGANIZER. Graphical output (white char- acters on black background) on the T/S 1000 by ORGANIZER is straightforward, requiring only use of the graphics key. The same is not true, however, for VU-FILE print- outs by the 2068!!! VU-FILE refuses to print-out white characters on black background."

Ron Ruegg Baton Rouge, LA

“As I was skimming through the Sept/Oct ‘85 editicn of TIME DESIGNS, I was "shocked" to see a joystick appli- cation program which used the exact same algorithm 2s mine. My first thought was: How dare Mr. Fricke (the author), use his name on my software. Then I reflected. How could Mr. Fricke have gotten a hold of my ingenious software in the first place? I hadn't even published it yet. Logic prevailed and I concluded that both Mr. Fricke and I had independently devised an identical algorithm for the same purpose; That of BASIC joystick control for the T/S 2068 computer.

.My next step was to verify if both algorithms were indeed identical. I dug deep into my vast library of 2068 programs, and low and behold, there it was; written almost two years prior with no witness to the event other than my own personal documentation. Only the variables were different. Where I used x and y as coordinates, Mr Fricke used the more meaningful variables c and 1, for column and line.

I had always intended on submitting my joystick pro- gram for publication but so far it had been easier to find an excuse not to. Although I realized this simple Program could benefit the T/S 2068 community at large, I did nothing to encourage this fact. The bottom line being “I am a procrastinator" ("I'l1 do it later").

You can imagine my suprise then, when 1 saw "my" Program credited to someone else's name. My first re- action was one of disbelief and surprise, followed by anger (at myself), next of jealousy and finally redemp- tion. The next instant, I found myself wuwing...which brings me to the "here and now" and “what are you going to do about it (?)".

First, I would like to commend Mr. Warren Fricke of Depew, NY, for his initiative in submitting an ingen- iously efficient, yet simple algorithm for BASIC joystick control for the 2068. Commendations are also forthcoming to Mr. John McMichael of Bozeman, Montana for having in- spired Mr. Fricke in the first place with his MC joystick program published in TOM (May/June '85). Credit also goes to editor Mr. Tim Woods, being first to publish these algorithms in his leading journal TIME DESIGNS Magazine.

Second, to all you prospective programmers: send in your ideas and programs. There are at least a half dozen leading American T/S periodicals, waiting and wanting for your INPUT. You have nothing to lose and so much to gain and so do we. You may even get royalties for your work if its up to standards. Do as I say, not as I do

Thirdly, having said all that and still feeling like a “shmuck", I set out to redeem myself..elsewhere in this magazine you will find MY program on BASIC 2068 joystick control. It is an enhancement to a program with which you are already familiar (if you have read this far), and has been reproduced in full for clarity of description. I call it JOYSTICK WRAP AROUND. I trust good use will be made of it."

EDITOR: Thank you Mx. DeBoniface for your story with a moral, and a "happy ending”.

128K AND ENIGMA

Reported by R. Lussier

The 128k Spectrum (code name has been launched in Spain, and available in the Spring in Britain.

Essentially two computers in one: when turned on, the 128k mode is on automatically but type "SPECTRUM", and it becomes a 48k Spectrum Plus, completely compatible with all the existing Spectrum software. The UK model will sell for about ¢150.

The 128k looks like a Spectrum Plus with a big heat sink bolted on the right- hand side, and a separate [numerical] keypad attached by a coil-cord into the front of the Spectrum. A full range of ports have been included: an RS232 socket, MIDI sockets for musical instrument hook-up, RGB/com- posite socket and TV socket. The tape leads are on the left-hand side, and the edge con- nector is in the usual place. There is a SOUND chip as on the 2068 (but SOUND is thru the TV speaker and adjustable.

In the 128k mode, the keyword system is not used. They are entered one letter at a time, but keywords are retained in the 48k mode. The 128 has the capacity to act as a

"Derby" ) will be

RAM disk system. This is a facility where areas of RAM can be set aside to store a suite of programs or sets of data, in much the same way as on the Microdrives. Access to files on RAM disk is almost as instan- taneous. As an example, the command "CAT", produces an instant catalog of RAM files.

There is still no sign of a joystick port.

There may be a few changes before it appears on the British market scene. It looks to be a strong base model for the new Sinclair range of models including the new

portable PANDORA and the desktop ENIGMA. It is stated in the current catalog of the EMC (15 Kilburn Ct., Newport, RI 02840) that they will be carrying this great new product [Editor's Note: reportedly the English Micro Connection now has the Spanish version of the Spectrum 128k available now for $259.95 plus $10 P&H. The keyboard, screen text and users manual is in Spanish]. If interested, then contact them for more information.

The ENIGMA will be Sinclair's first “"Mega-machiche". Sinclair believes that one Megabyte RAM is a minimum needed to compete

SINGLAIR N

IE TWOIIK

with Atari's ST and the Commodore AMIGA. The ENIGMA will also have two 3.5 inch disk drives. It is planned for launch in May 1986

between ¢500 to ¢1000 price range. The pro- grams QUILL, ABACUS, ARCHIVE and EASEL will be on ROM. It will also have full window, icon and mouse environment, as well as GEM (used on the APRICOT computer). The Enigma will be sold as a complete package. This will include software, drives, mouse, color monitor and printer. It may also develop the addition of phone and communications work

station.

AN AMERICAN ORIGINAL

Most colorful and popular arcade-type game programs are instantly associated with the British Spectrum. Until now that is. An American programmer, John Coffey of Scotts- burg, Indiana, has developed a brand new arcade game called "DIAMOND MIKE", for the un-modified 2068. This is the first program of its genre, written in 100% machine code, that has been released here especially for the 2068, in the last two years. Due to the author's thoughtful placement of code in memory, Diamond Mike also runs on the Sin- clair Spectrum (or 2068 with Emulator). Mr. Coffey is the owner of a software company called JRC SOFTWARE. He has also written the 2068 COMPASS assembler/compiler package, the T/S 1000 SUPERTAPE, and 2068 GREAT GAMES and GRAPHICS SHOW.

DIAMOND MIKE (as the name suggests) is a cute little character who craves diamonds. He impatiently stamps his foot, waiting for you to guide him thru the diamond mine. All along the way are boulder-sized obstacles that could have "deadly" results. There are also attacking amebas and butterflys (?) to watch out for. The game has a lot of person-

ality, and is addictive.

On the same tape is a bonus program called CAVERN. It is a space game imported from Canada. There is also an "electronic"

catalog, that describes other programs being offered by JRC Software. An impressive (and unique) Diamond Mike, is the users ability to SAVE a short demo version of the game to pass along to a friend. Over all there are 22 different

feature of

screens/puzzles,

and six levels. At its $17.95 price, JRC Software (PO Box 448, Scottsburg, IN 47170) will be selling lots of DIAMOND MIKE copies this year.

QUICKEY 2068 is a series of keyboard

overlays that assist the user in remembering important commands for selected popular pro- grams like TASWORD II and MSCRIPT. The over- lays are made of durable plastic and have the commands printed on the top-most section (above the keyboard), so the user does not have to glance down at the keyboard itself.

The Tasword version of Quickey 2068 in- cludes commands for TASPRINT. Other overlays will be available soon, for programs like OMNI-CALC, ect. There is also a blank model available that the user can customize to suit any need.

AN-TO PRODUCTIONS (9009 West Elm St. #2 Phoenix, AZ 85037) is the developer and dis- tributor of the Quickey 2068. Prices for the Tasword and MSCRIPT versions are $3.99 each plus 50¢ for postage. Blank overlays are $3.00 each. Any two versions can be ordered for $7.50 plus 50¢ for postage.

“WHY THE QL?” HANAN

REASONS WHY YOU SHOULD TAKE THE QUANTUM LEAP

- - momcaces by Mike de Sosa

Why should you consider the purchase of a SINCLAIR QL? Why, possessed of an excel- lent and only recently fulfilled system such as the Timex/Sinclair 2068, should you go to all the trouble and expense of switching systems--just think of the problem in tran- scribing your current files to Microdrive format? And why purchase a system that Sin- clair Research doesn't seem proud enough of to advertise, and which some have said is Uncle Clive's first computer failure? Why opt for the QL instead of your current sys- tem, another reasonably priced wunderkind computer such as the new Atari, Commodore, or Amstrad, or, perhaps, a somewhat more expensive IBM PC-compatible? Finally, why consider a system which reviewers have gen- erally panned? There are many excellent and indisputable reasons why you should consider such a purchase. Here are a few. many others.

COME TO THE FAIR

Plans are being finalized for the MID- WEST TIMEX/SINCLAIR COMPUTERFEST to be held in Cincinnati, Ohio on May 3 and 4, 1986. On hand will be vendors, services, and users groups. Also planned are classes and lec- tures by guest speakers, hardware and soft- ware demonstrations, and a "swap-shop". A major goal for the T/S COMPUTERFEST is to introduce the wide scope of products and

services available for the discontinued T/S line of computers, and perhaps new practical uses for these computers.

A_ Best Buy!

At the moment--and things do change-- the Sinclair QL, with its compact and effi- cient keyboard console, its 32-bit CPU, its twin Microdrives, its excellent operating system and highly regarded SuperBASIC, its exceptional "bundled" software, its compre- hensive user guide, and finally, its avail- able hardware and software support, is a "best buy" by a considerable margin at $299. The U.S. version of the QL, its firmware, and its four semi-integrated software pro- grams~-now in their fourth or fifth version, comprise a mature and system for which dozens (who really needs thousands?) of excellent software programs and numerous state-of-the-art expansion and mass~storage systems are now available.

The QL Keyboard Console

The 3-pound keyboard console--a triumph of design and engineering, recognized as such by the Museum of Modern Art--includes all QL components except a separate one- pound power supply. QL components include two CPU's, the 32-bit Motorola 68008 (cousin to that in the Apple Macintosh) and the 8- bit Intel 8049; four additional Sinclair- designed ICs; a full-sized, 65-key QWERTY keyboard, first-class in most respects but with no numeric keypad; built-in Micro

More than an expanded Timex/Sinclair 2068 BASIC, Super- BASIC offers much greater flexibility than previous versions. User-defined procedures

and functions--callable by name without ref~

erence to line numbers--may be used to ex- tend an already much-enlarged SuperBASIC vocabulary. Data is more readily transferred between variable types, with string vari-

ables accepting numeric data and vice versa Repetition, decision-making, other logical and array-handling are

The results presented in this article were obtained with a T/S 1500 and may differ from those obtained with the T/S 1000 with- out a 16K RAMPACK.

The readers with a T/S 1500 and those with a T/S 100 who own 3.25K or more of RAM

have their choice of three trails (Operat- ing Modes) they can use to traverse the RAM Jungle:

1. Both the Actual RAMTOP and the system variable RAMTOP set at or above address- 19712.

2. Actual RAMTOP at or above address 19712,

but the system variable RAMTOP POKEd to less than 19712, without ENTERing NEW. 3. Both the Actual RAMTOP and the system variable RAMTOP set below address 19712. In all of the modes the program must be able to operate in the amount of RAM, to which Actual RAMTOP is set. Actual RAMTOP is one address higher than the top of the GOSUB stack (GS stack). Both Mode No.1 and Mode No.3 have a sub-mode available where the

less than the Actual RAMTOP whithout ing NEW. The T/S 1000 without an additional RAMPACK, has 2K RAM (maximum Actual RAMTOP address 18432) and can only use Mode No. 3 and Submode 3. The Submodes are used in a program when it is designed to store data or machine code in the Safe Area with NEW in a program line so that the strings and vari- ables, along with the program, will be de- stroyed, in order that a new program can be LOADed that will utilize the data or machine code. Mode No.2 can also be used for this purpose. The main use of Mode No.2 is to save memory when a program will not operate in less than 3.25K RAM and a full screen is not used in the program.

ENTER-

Mode No.2 can also be used when recording a program in order to save time or tape, as there are 768 bytes less in the display file be recorded. Mode No.3 can also be used for this purpose. A program SAVEd while in Modes 2 or 3 can be LOADed into the computer when it is in Mode No.1.

Part One of this article (published SEPT/OCT '85) covered the GOSUB and Machine stacks also determining the upper limit of

to

system variable RAMTOPis POKEd to an accress@the Safe Area. Part Two of the article (pub-

lished NOV/DEC '85) covered the Calculator Stack (C stack) and determining, while in Mode No.1, the lower limit of the Safe Area and the minimum setting for RAMTOP, that would allow the program to operate. If a program will not use a full screen display, RAMTOP can be set even lower, saving ad- ditional memory above RAMTOP for storage of

data. To determine this absolute minimum setting for RAMTOP that will allow the pro- gram to RUN and the computer to act nor-

mally, we can use either Mode No.2 or, if the program will operated in less than 3.25K

of RAM, Mode No.3. For the purposes of illu-

stration of the features of Mode No.2 to those readers with 3.25K or more RAM, we will use this mode for them. Readers owning the T/S 1000 but only 2K RAM will also be able to join in RUNning the examples, and obtain similar results.

Readers with more than 16K RAM, set

RAMTOP to 32768 as follows:

ENTER POKE 16388,2 ENTER POKE 16389,126

ENTER NEW

All those readers with 3.25K RAM or more are now ready to cross over the Great RAM Divide, located at address 19712, into the domain of less than 3.25K RAM. We will do this by POKEing the system variable RAM- TOP to address 18432 (the same as if we had 2K RAM) without ENTERing NEW as_ follows:

ENTER POKE 16388,0 ENTER POKE 16389, 72 ENTER CLS

A minimal display file has now been set up, but Actual RAMTOP is still 32768. To this, ENTER the following: PRINT PEEK The top of the GOSUB stack marker, decimal no. 62, will not be printed on the screen. If you PRINT PEEK 32767 it will be printed on the screen.

To prove that a minimum display file has been set up, PEEK the system variables VARS and D_ FILE by ENTERing the following:

PRINT (PEEK 16409+256*PEEK 16401 )-(PEEK 16396+256%PEEK 16397) The value displayed should be 25, the number of bytes in a minimum display.

To find the absolute minimum address to which we can set RAMTOP for Program One that we used as an example in Part Two of this article, we must type in the program and

prove

SAVE it on tape while in Mode No.2 (T/S 1000 2K RAM in mode No.3). Type in Program One as follows:

10 FOR N=1 TO 48

20 PRINT PEEK 16412+256%xPEEK 1 6413;"" "5

30 NEXT N

SAVE this program on tape.

As we want a completely clean memory in order to determine the upper limit of the Safe Area for Program One while in Mode No.2 (or 3), turn off the computer. Then power up. Those with over 16K RAM, set Actual RAM- TOP to 32768 as covered above. All but those with 2K RAM, POKE the system variable RAMTOP to address 18432 without ENTERing NEW as you did before. Everyone LOAD and RUN Program One. Your results should agree with Figure No.1. Each time through the loop the program prints the value contained in the system variable STKEND and illustrates how every- thing above the expanding display file is moved up in memory. Find the upper limit of the Safe Area by PEEKing the addresses below RAMTOP-50 until you find the start of the Addresses containing only zeros. This should be 32715 for Mode 2 or 18379 (Mode 3).

PEEKing either the system variable STKEND or STKBOT using the direct double PRINT PEEK command, you should get 16667. We

will investigate the reason for this value later.

Looking at Figure No.1, the first two values in line one and in line nine are not the addresses of the top of the C_ stack. They are due to a "Giant Bug", beacause the

system variable STKEND is used by the Wicked Wizard of ROM for some other purpose than pointing to the address of the top of the C stack. What about the other values of Fig. No.1? Change line 20 of Program One to read:

2M PRINT PEEK 16410+256*PEEK 1 64143" 7;

Each time through the loop the value stored in the system variable STKBOT will be print- ed. RUN the program and your results should agree with Figure No.2. Each time an address is printed, the bottom and the top of the C stack are moved up another six addresses as the display file is expanded by that amount.

Note the correlation between Figures No.1 and No.2. The addresses in Figure No. 1, other than the first two of lines 1 and 9, are the same as those in Figure No.2, and

are actually the addresses of the bottom of the C stack. Therefore we cannot locate the top of the C stack while the program is RUN- ning by inserting a line in the program to PEEK STKEND.

Let us investigate why we get 16667 as

10°° bottom of the C stack using the direct

command to PEEK STKBOT or STKEND programs print the last value as 16912. When a direct command is ENTERed, the first thing that happens is the screen is CLEARed. As we are dealing with a minimal display file, the C stack is moved down before the command picks up the value stored in STKEND or STK- BOT, so we must add the number of characters on the screen to the 16667. The last six characters (including the space) are print- ed after the value is picked up. Therefore we have: 9*32-6=282 characters The direct double PEEK command, in Part Two of this article, increases result by thirty-seven, so it must be tracted. Therefore: 16667+282-37=16912 Which is the same as the last value of Fig- ures No.1 and 2.

We can locate the maximum address of the top of the C stack during the RUNning of the program by laying down some fly-paper with Program Two of Part Two of this series. Changing line 10 to fit the new addresses the program now reads as follows:

19 FOR N=16912 TO 17158

when the

As repetition is the core of learning, let us find the minimum setting for RAMTOP of a more practical program. Figure No.3 is an outline for a "bare bones" text entry program. When complete, it will display the text as it is entered, and store the text above RAMTOP. Line 80 redefines the ENTER key as the SPACE key, because both the PAUSE and INKEY$ functions turn the SPACE key into BREAK when shifted or unshifted. To quit text entry, use STOP. The STOP is stored as the end of the text marker (line 100). The

3) Assuming we do not know if the program will RUN in less than 3.25K RAM, readers with this amount or more should chose Mode

Temporarily, since we will be working in Mode No.2 (or 3) and we need to exactly fill the screen with text, so that the display file will be expanded to the maximum for 22 lines, we will use A=B-703 bytes. Change line 10 to read: For Mode 2 10 LET A=32064 For Mode 3 10 LET A=17728 5) Change line 20 to read: For Mode 2 20 LET B=32767 For Mode 3 20 LET B=18431 6) Type the program as changed above into the computer and record the program on tape, while the computer is in Mode No.2 (or 3). 7) To insure a clean memory, turn off the power. Power up. Set Mode No.2 as in 3 above (3.25K RAM or over only). LOAD the "Text Entry" program. RUN the program, typing in text until the screen is filled and you get a 0/160 report. There is no cursor or cor- rectional features!

8) Find the upper limit of the Safe Area by PEEKing the addresses near RAMTOP-50. This will be 32717 (T/S 1500 Mode No.2) or 18389

(T/S 1500 Mode No.3, Actual RAMTOP at 18432) As you can see, setting Mode 3 in the T/S 1500, not only sets up a minimum display file, but also changes the operating system as regards the M stack. To be on the safe side, never use a value for the upper init] eT

"Experimental the T/s

Software 1000/1500 and

For those who would like to enlist their computer in some interesting experiments color illusions, this program offers a rare opportunity to investigate "Subjective Color- ing". Bill Russell, developer of the computer concept, has worked out a very interesting program that will produce in a graphic manner the colors: RED, YELLOW, BLUE, CYAN, and GREEN.

The taped program provides an image that does this very thing (for some people). The user can also produce images of choice as

in

Bill provides the parameters for doing this. Granted, there are restrictions as to image drawing in terms of space between different colors. Two methods of drawing are provided.

One is to draw the shapes by what amounts PLOT, as the lines are 1/4 character size. The second method is more complicated as it is more like defining GRAPHIC shapes by using the GRAPHIC keys and character keys, and specifying spaces down and spaces over for the graphics you want. This method permits the use of letter shapes as well as graphic shapes.

There is provision in the program to SAVE graphic shapes, so that further study/ demonstration is possible. You can even alter a shape after it is LOADed, thus experiment with different degrees of color separation.

The method developed to give a color effect is to produce each different color by vibrating or pulsing the black image that corresponds to the part of the picture that is assigned that color. This is done, by sim- ply specifying a color for those parts to be so colored. Each color pulses at a different rate that has been determined by tests. The experimentor can vary the black/white flash- ing rates to study this phenomena.

How well does this illusion work? It indeed in the eyes of the beholder (or the brain?), as different people see

The concensus of viewers was that for some, there was color, but very dim or muddy. The author makes no pretense about this as the system is intented to produce an illusion in the mind that there is color.

The demonstration image [supplied on the tape], full screen, had me puzzled as to where the green color existed, so I printed the screen for each color on a 2040 printer. The image for each color was then known, so 1 studied the screen again knowing which lines to look for. I doubt that this convinced me. I haven't yet persued a study to enchance the colors.

This program

can provide considerable discussion for groups as it certainly brings up to date a method, first discovered 100 years ago, of stimulating the nervous system with pulsing black and white.

The documentation is very good, written in the Bill Russell "style". Besides a com- plete instruction of use, he has included explanation of the BASIC program, and the machine language with mnemonics and dresses, and a description. This is a in itself. There is also provided a cut-out Benham Subjective Color Disk, to try the original experiments. He also provides an amber-colored screen filter (10 x 12 inches) to be taped over the B&W TV screen. Price for the CHROMA-SOFT program on cassette is $14.95 from Russell Electronics, RD 1, Box 539 Centre Hall, PA 16828.

Linear Programming, is the minimazation or maximazation of a linear form,

linear constraints, containing

subject to non-negative

variables. The program I have written, uses the "simplex" method to do this.

The linear constraints are used to model certain physical situations, and the

linear form that is optimized, tells how the situation that has been modeled, reacts to changes in the variables.

The program that I have the mimimum of the linear function and _ the value of the variables used. The array S contains the column numbers of the variables having been solved-for, starting with the first equation and going on down to the last constraint equation. For example:

and 3/4" in diameter, with a fixed length of three feet. They sell for one, two and three dollars per dozen respectively. Fifty of 1/4 and 3/4 inch dowels, together can be be made from one piece of wood ( if the wood is good). Seventy-five of the 1/4 and 1/2- inch dowels can be made if the wood is good.

To conserve wood, two 1/4-inch dowels are made after each 3/4-inch dowel is made. How many of each size dowel, should be made to maximize profit, from each piece of wood?

maximize Z= $1.00 x1 + $2.00 x2 + $3.00 x3 subject to 2x1+ + 1 x3@ 50 1 xl+ 1 x2 < 75 x170, x2p0, x3y0, X4y0, X5p0 To minimize Z, we take the negative of -Z, i.e.; -(-Z). The answer: x3=50, x2=75, z= $300.00, x1=x4=x5=0 where x1= the number of 1/4" dowels made x2= the number of 1/2" dowels made x3= the number of 3/4" dowels made fo put the problem in a form the computer can use, we need to add slack variables x4, and x5 where both x42?0 and x5>0. then the problem is: maximize Z= $1.00 x1 + $2.00 x2 + $3.00 x3 2x1 + x3 + x4 + O.x5 =50 x1 + x2 +0x4 + x5 575 xipOQ (i= 1,2,3,4,5) and we find (- minimum (-Z)).

by Rick Borland

"TURBOS" is a computer program that I wrote for engine building enthusiasts. I will try to explain how it works and what it does.

By taking an engine that has no turbo, blower, ect., and using it's rated horse- power, the rpm's it was rated at, and the engine's cubic inch displacement, one can figure the cubic feet of air flow through the engine and thus calculate new horsepover J@

vatings and cfm rates at different turbo beost pressures, Most "outright" sold turbo systems have 6 to 15 psi boost. Racing and pulling engines have higher boosts. But any- way you look at it, heat is generated when air is compressed, thus creating new prob- lems at higher boost figures, Cooling the incoming turbo-compressed air, helps to in- crease power at lower temperatures. This method is called "intercooling", and can be dene in the outside air, or through the engine's cooling system (thermostat temper- ature). At low boosts, intercooling is not helpful, but actually hinders results. But calculated results are interesting. Actual engine results will be slightly less due to friction.

Use the program as follows. Input all figures asked for, keeping in mind that out- door ambient temperature ratings are almost always 70°F or 80°F when calculating engine figures. Engines rated in size by "cc", can be converted (1 liter = 1000cc = approx. 61 cubic inches).

When entering cooling modes, air to air will be outdoor temperature in “F°", and air to water will be the engine's thermostat setting "F°", The program rounds out all calculations to the nearest hundreth.

All calculations in the program, as far as temperature go, are figured in "absolute temperature". Everything else in the program comes from physics of turbos, derived from formulas used by tractor manufacturers, but works well for almost all calculations of engines. The program prints out on a stan- dard Timex 2040 (or comparable) printer.

Any questions? Please direct them to me and I'll answer them as best as I can.

GAMESMATE FIX

by Steve Wyatt

Those who have purchased the GAMESMATE Kempston compatable joystick interface have noticed conflicts with other add-ons such as the AERCO disk interface. This is due to the minimal decoding techniques used by so many of the third party peripherals, including the GAMESMATE, for the Spectrum and 2068. Further decoding can be accomp- lished relatively simply and without add- itional parts, that will resolve most of these conflicts. Understanding the circuit isn't necessary, so if you wish, refer to

may

FIGURE 1 and make the changes.

Essentially, two more address AG and A7, being brought into play. Originally, if I/Oreq was low(active) and A5 was low(inactive), the joystick would be enabled. Thus the GAMESMATE I/F would be active every time an I/O operation was per- formed and A5 wasn't used. By bringing A6 and A7 into play, we can effectively re- strict the joystick to an I/O address of 31 decimal/1F hex and below. The first move is to cut the trace (marked with the X) run- ning from pin 6 of the LS32 to pin 1 of the LS244, A6é and A7, marked A and B at the finger connectors, are jumpered to pins 1 and 2 of the LS32, and the output is then respectively taken from pin 3 and jumpered to pin 10 of the same chip. Pin 6 is jump- ered to pin 9, on the same chip.

After trying for two weeks to convert PRO/FILE 2068 so that the files may be saved separately from the program...I gave up. I tried to use both an early and a later ver- sion of the program. This is an excellent data base program, and really needs to have one more rewrite to be fully useful. It may be possible to save the files by re-saving the complete program every time you add to or start a new file. But you would have to be extremely careful to keep separate discs for different files.

One further bit of information. Be ex- tremely careful about formating discs with a

program in the computer, and also using the erase option. This can cause the disc to crash and the loss of all information on

that disc.

"+ STRS a:HOVE"AS"

Finally we can take our new enable signal to the LS244 by jumpering pin 8 of the LS32 to pin 1 of the LS244,.

This fix doesn't work on the Graphics Tablet, which is mapped in at 0- 16. Your questions and problems can be directed to Steve Wyatt (301) 779-7743. I would like to know if this fix works with the A & J Mikrodrives.

JOYSTICK WRAP AROUND

The following BASIC for the T/S 2068 computer is an to an original by Warren Fricke, first lished in TIME DESIGNS Sept/Oct 1985 No.6).

Keeping the flavor of it's predecessor, program does no more than demonstrate new potential. Possible applications be dealt with later.

There are two lines of code which make this program tick. All else is These two lines are the ments for "column" c and and 370).

These two assignment statements effec- tively replace over three dozen IF state- ments. It reminds me of APL, where the epit- omy of programming code is; "See if you can cram it all in one line". This architectural marvel is made possible by what is known as “BOOLEAN LOGIC AND RELATIONAL OPERATORS".

Boolean Logic, also known as _ Boolean Arithmetic, is named after George Boole, a 19th century English mathematician and log- ician. Relational operators are also known as Binary operators. The T/S 2068 user's manual outlines these very briefly page 228.

HOW IT WORKS: In a nutshell, all I have done is include the statement (-x OR ...) twice, within each assignment statement for 1 and c in the original BASIC joystick tine (see TABLE 1).

-x is the parameter limit for each axis -31 for horizontal, and -21 vertical. Sin- clair BASIC only allows 0 to 31 characters horizontally and 0 to 21 characters vert- ically.

The inclusion of this bit of in the antecedant program, not only cktecks for range limitations (eg.<0), but acts on them as well. Should the joystick direct the cursor beyond the screen range, the limit is reassigned to it's opposite value.

What does this mean? If you try to go beyond column zero, the cursor is reassigned to the opposite side of the screen and pops up in column 31. Or, if you pass through the right side of the screen, the cursor “wraps

First, load the driver your interface, and save it to a blank tape. DO NOT REWIND THE TAPE! Next, type in the simple program below. SAVE this on the tape immediately following the driver. Make sure to use the LINE command on the SAVE so that it will auto-run.

That's all there is to it! Just one note...If you plan on using double quotes ("), such as LOAD "", you will need to in- put TWICE the amount you will want printed. LOAD "" will need to be inputted LOAD

As the next few months go by, we will be going over how to use the "Tree Struc~ ture" operating system of the drives, to

develop many directories and related files

on one disk. We will also be going into depth on the two file systems supported by these drives...random access and sequential

files.

Continued Next Page

Its the first of these file systems, or Random Access files, that is the most ex- citing. By using random access files, we are now in the position of using our drive sys- tem as a "disk RAM". That means that because of the speed that the drives work at, we can use the disks to store information and specific information to our programs domly. Large data files, such as a book program, will just access the mation you need, and not the entire file.

File storage is what sets this system apart from the cassette recorder. Now I know what you are saying. Its the speed that sets this system apart from cassettes. Well, that is only half true. It breaks my heart to see people spend the $350 bucks for a state of the art disk drive system, and use it for just saving and loading programs. No, it is the way that we manipulate our data files, and not have their size be limited by the computer's memory, that sets this system apart from the cassette recorder.

Whew, sorry about that soap box I just get that way when I think powerful this system is.

Other articles will include using the RS232C ports with a Hayes 1200 modem (I do it now), as well as hooking up aé_e serial printer to them. We will also look at exist~ ing programs for the T/S 2068, and how we can convert them for use on the D.D. system.

On that vein, there was one program that I used more than any other, and that was TASWORD TWO. One of the first things I did was to convert it for use with the D.D. system. Lets see how this is done.

send ran- phone infor- data

can

stuff. about how

The first thing you must do is to exit the program and get into BASIC. Go to line 15, and change the part about LOAD “tascode. cod" to LOAD* "tascode.cod". Next, go to line 700 and 710 and put an * in front of the SAVE commands. After that is done, go to line 1030 and do the same for that SAVE command. Just one more line to go...line 2030. There you put an * in front of the LOAD command. Type in GOTO 700, and _ there you have it, TASWORD TWO on the Zebra Floppy Drive System.

Now while that is a bare bones change, in the October issue of L.I.S.T.ing (the user groups newsletter from Long Island, New York) my best friend Andy Gippetti did an in-depth conversion of Tasword, that makes it even more powerful. Andy's conversion allows for files from both cassette and disk to be used, and gives you a CATALOG option in the main menu. For a copy of this article or any other statements you may have, feel free to write me at: 21 Regina Dr., Sayville New York 11782. You can also join L.1.S.T., or a more local users group that gets the LIST newsletter. Well, bye for now!

OS-64 Reviewed by Tim Woods

One way of looking at the OS-64 Cart- ridge Software, is an "unfulfilled promise" that has come true for the 2068.

All manner of cartridge-based software was to have had a perfect marriage with this computer, such

as languages, CP/M, ROM expansion, utilities for bank-switching, and yes, utilities for the extended video modes. The 64 column text mode is one of these modes, that up until now, has barely been utilized (on a wide- scale basis).

The OS-64 Cartridge is a small pc board with an EPROM, a decoder IC, and with a thin plastic housing that is spray- painted black. It is somewhat larger than an original Timex cartridge, and has a snug fit when inserted into the dock of the 2068.

The accompanying manual is 12 pages long, and outlines the basic functions of the OS-64. While the language is clear and straight-forward, I have the feeling that some users will want to receive additional information not covered in the manual. Such as an in-depth explanation of how this new system "works", along with system ROM calls, and more details on printer/interface oper- ations.

There are a few limitations that should be pointed our to prospective purchasers of the OS-64. First, it support the printing routines of the Timex 2040 printer. Instead, it has built-in print drivers for the AERCO, Tasman, A&J, and Oliger printer interfaces. The system defaults to the AERCO (but a simple POKE will select the correct one). The trade off for the 2040 is the full size printer facilities.

covered

rather cartridge

doesn't

OS-64 doesn't use the command FLASH. PAPER and INK have limited effect, and are

pre-determined, All graphics commands work normally (255x175), however, the 512 pixel- width mode is accessible by machine code. All other BASIC commands are normal, only now PRINT, LIST, LPRINT, LLIST, ect., are in 64 columns.

When the 2068 powers up, it re-initial- izes, and the OS-64 takes over. A quite noticeable white characters on black back~ ground screen appears. There is no border, as all of the screen is now used. I have only used the OS-64 with a color composite monitor, and the small character definition is fairly readable. The user manual strongly recommends the use of a monochrome or RGB monitor. This would reduce eye-strain over a period of time.

One of the impressive "effects" of this system, is LISTing a BASIC program...no more

"wrap-around" of program lines, all infor- mation for a line number is on one 64 col. line. This allows for easy editing and de-

bugging of programs.

The other important aspect of the OS-64 would be in software development especially for this operating system. I had the opportunity to preview two such programs.

The first program is called PERSONAL SECRETARY. Unlike other common appointment managers, you can now see a whole screen full of appointments, along with a calender of the month you are working with. Very nice touch. My copy of Personal Secretary was previewed on the Zebra Systems Disk Drive system. Together with the floppy drives, and the O0S-64...it was a SUPER operating system!

The latter program, is one that you may already be familiar with, if you read my re- view of the VIEWORD word processor in the NOV/DEC 85 issue of TDM. Only this is a new version that works with the OS+64. There are many new enhancements (including 64 col. of course) that makes this good little Processor an even better one.

The OS-64 has a few drawbacks, but it does turn the 2068 into a "professional" style operating system. Outside of the Spec- trum Emulator, I haven't seen a better use for the 2068's cartridge dock. Put into the right developer's hands, some very interest- ing and practical software could be written.

OS-64 is available from Zebra Systems, Inc., 78- 06 Jamaica Ave, Woodhaven NY 11421) for $29.95 plus $3 for total order P&H. PERSONAL SECRETARY also available from Zebra on cassette or 3 VIEWORD is available from Jim Clatfelter,

Tech—Draw Junior

Tech-Draw was created for the TS2068 Zebra Graphics Tablet System. Now, to bring you most of the power of Tech-Draw without the expense of the graphics tablet,-we have created Tech-Oraw Junior.

Tech-Oraw Junior is functionally identical to the original Tech-Draw except for that you can now use a joystick instead of the graphics tablet to control Tech-Draw's functions.

Tech-Draw was described in our last two Zebra Catalogs and has received favorable reviews in the following mazazines:

TIME-DESIGNS Sept/Oct 85 Page 17...

“the Zebra Graphics Tablet and Tech-Oraw are excellent"

TS HORIZONS May/June 85 Page 21....

"my prediction of the Program of the Year: Tech- Draw"

SUM MAGAZINE August 85 Page 1...... "Tech-Draw is very professional and puts this system in the same league as say the MacPaint series for the Apple”

Tech-Draw Junior supports the following printer interfaces: AERCO, TASMAN 8 & C, A&J, Zebra FOD Serial, and the following printers:

TS2040, ALPHACOM/32, EPSON FX & RX, GEMINI 10x, STAR MICRONICS SG-10, MEMOTECH OMX-80, PANASONIC 1090/1091, CITOH 8510, SEIKOSHA GP250 & GP100, GORILLA BANANA, OLIVETTI PR-2300.
