Ian Robertson SINC-LINK August 1985 UPDATES: J want to thank all of you who wrote to ae with advise and comments on just what you would purchase, i.e. disc, watadrive, microdrive (both Sinclair and Ak J), Spectrum, Portugese 72048, etc. To bring you up to date I bought a Spectrum Plus, Interface 1 and 2 Microdrives. There sure are quality problems at Sinclair! For exasple - one of the drives was perfect while the other was aot (I am being kind), the cable joining the drives to Interface 1 had an intermittent opea circuit and the heat sink inside the Spectrum was barely held on by the bolt through the regulator/board. But once those items were corrected I as glad to report that all is runaing well and lives up to expectations. The drives are actually quieter than I anticipated and the access/loading times are quite acceptable. finally got Hisoft running and beleive it or not it was that dreaded "tape recorder output" problem that we all know and do not admire, It took 7 recorders until I found one that would work .It was the 152020 with a 7.5 volt DC power supply that did the job. Since purchasing ARTWORX (RANEX INTERNATIONAL 1762? 26 MILE ROAD WASHINGTON NI 48094) I have been pleased with the User Friendly aspect of it. As if this needed reinforcing I purchased another program of this type called THE ARTIST (Softek Int). While this is the top rated UK Spectrum progras {according to the June issue of YOUR SPECTRUM), it not only Jacks some of ARTWORX sophistication but is also far from being User Friendly. All things considered ARTWORX is stil] a BEST BUY.

TS2068 The big news is the number of disc drive interfaces ዘፀ now have to choose from WHAT A DIFFERENCE! On the local scene we have one from LARKEN ELECTRONICS, R.R.2, NAVAN, ONTARIO, KOA 250, telephone 613-835-2680. It is a very reasonably priced and very wel] assembled controller board complete with all cables and connectors. For $117.95 ($89.95 US) plus shipping, you get an interface that is compatible with the

192068 and the Spectrum emulaotor, At the aonent there are tno

happy TSUG members whirring away with this system, It supports one Shogart SA455 DSSD drive (160k total). While this say not seem like a Jot, think of those thousands of happy Apple Users with only 128k and one drive! The DOS is on a 2k eprom and on a supplied disc. ለ5 iaprovesents are available you will be notified and an updated eprom will be available. ALL THINGS CONSIDERED - THIS ITEM IS ANOTHER BEST BUY. One other new disc system is the 3" Timex Portugal being sold by Bob Dyl of THE ENGLISH MICRO CONNECTION 15 KILBURN COURT NEWPORT RI 02840 telephone 401-849-3805. The discs are available Jocally from Exceltronix at 319 College St. 921-8941. The Portugese system will also be carried by ZEBRA SYSTEXS 78-06 Jamaica Ave. WOODHAVEN NY 11421 telephone 718-276-2385. The yet to be released disc systes of John Oliger/Ray Kingsley from THE JOHN OLIGER CO. 11601 WHIDBEY DR. CUMBERLAND IM 46227 sounds like a winner tuo. It will consist of 3 boards (eventually) and the specs. iizicate that it will be hard to beat. For information send a BASE to Jahn at the above address. Good news for anyone requiring 192048 repairs. The following two locations ዘ111 perfors repairs, {1) TS CONNECTION, 3832 VATTERSON, CINCINNATI, OHID 45227, telephone 513-271-5575 troa 8 aa to 10 pa EST, (2)


SPECTRUM There are several new and some not quite 50 new programs that have simply blown ዘሃ aind, 111 name a few BETA BASIC 3.0 (update of version 1.8), MEGA BASIC (from Your Spectrum), BLAST (a truly sophisticated compiler), SUPERCODE 3 (toolkit with 152 utilities}, MUSIC TYPEWRITER {compose/play ausic and prints out 80 column) and ALIEN 8 (game), All of these are available from Bob Dyl at EMC. 50 far I've mentioned YOUR SPECTRUM twice and not elaborated. It is a GREAT Spectrua dedicated aagazine available from YOUR SPECTRUM, SUBSCRIPTIONS, 14 RATHBONE PLACE, LONDON WIP 1DE, U.K, at 825.00 (pounds Sterling). Like all UK publications they are quite gase oriented. They also take Mastercard and Visa, but be sure to Include your cards expiry date. I know they take plastic because that is hon I paid for ay subscriprion, back issues ard Mega basic. WARNING - if you buy U.K. software - make sure to copy it IMMEDIATELY upon receipt. I have had four tapes that either bind inside the case or break off inside due to binding, To sake matters worse, U.K. cassettes do not have screws. Therefore you cannot take them apart and add lubrication to the rollers like you can with Narth American cassettes. To add yet another insult to injury I have bad several U.K, tapes that are of such a low bias that they do not have adequate volume to load consistantly. This is where a Radio Shack mini amplifier helps. I am presently ‘in the process of adapting the Spectrum + from PAL ta NTSC and to use a composite video monitor. I have ordered the 152049 14,112 MHZ Yi crystal and will see what it does to Steady/upgrade the picture. More in my next columa. I have already converted the Sinclair power supply by replacing the transformer with a 115/18ሃር፲ 1 amp 60 HZ transforner,

TS1OOQ Exciting news! Peter McMullen’s ዘ08051ዘር 11.5 and WORD FONT V1.2 are finished, released and a copy of each is residing in ay ever expanding software library {300+ cassettes). WHAT A PAIR OF PROGRAMS! I4 you have a centrosics interface (either 151000 OR 752048) Peter will sell you a custom version tor it (lat the same price). This 518ዐ1ሃ means that if you are presently running a [52048 word processing system and you have a TS1000/2X81 hanging around - you ran put it to work , either as a backup system or as a seperate system (sharing the sane centronics iatertace), Al) this for $30.00 (WS 11.5) and $15.00 (WF V1.2) plus postage, They are available from PETER McMULLEN 2340 QUEEN STREET EAST TORONTO ONT. ዘጀ 169 telephone 416-694-3171, or trom INTEGRATED DATA SYSTEMS 30 BROOKMOUNT ROAD TORONTO ONT. NAL SNL, telephone 414-699-6380. IDS takes plastic. I have used both programs (more than once) and consider thes Comparable to using Mscript and Tasprint dtor the 152048) together lif that were possible). TRULY A BEST BUY!! The other ፳1805! impossible to believe item is the JOHN OLIGER VIDEO UPGRADE (or the JLOL000 Plus). This hardware upgrade makes your humble ፲21000/2፳81 into a flicker-free colour computer with upper/Jower case characters and a SLOW NODE THAT RUNS ALAUST AS FAST AS THE FAST MODE. What a way to liven up a Basic program! It prints out upper and lower case on either the 152040 or an 80 column printer (with the correct centronics interfacing). To use it you must have a composite video monitor. For further inforaation send a SASE to John Oliger at the address mentioned previously. THIS HAS BEEN A VERY GOOD MONTH FOR TS1000 USERS!!!!

Howdy, folks. Many of us just don’t fave auch time for hacking around with our computers in the summer acnths, but that doesn’t mean everything stops! I’ve heard several people say "the 7X81 market is dead" lately. Upon examining the current selection of ፲፤ሀ1/121000 software k hardware ads in 7-5 HORIZONS, SYMCHARE NEWS, TIME DESIGNS, and other magazines & newsletters, I'd say the aforegentioned people must have their ቁስ up some dark tole. The pickings are still rich: I’ve never seen a livelier “dead” coaputer!


Last issue, I printed a “correction” regarding interrupts š the John Oliger Video Upgrade- but I was right the first tine! My apologies to. John 01108", who sent àg the correct inforsation just a day too late to include it last tiae.

John says:

".,Regarding vectored Mode 2 interrupts and the Video Project: The Video Project DOES INDEED open up the use af Mode 2 interrupts. This hardware uses only the NHI interrupt and 881288 as a restart. No use is fade of the aaskable interrupts, 50 they CAN be used with the Video Project IF;

1] Ab is cut from the 180 INT line inside your computer.

2) pullup resistor is installed ሀበ the INT line (1K-10K ok) 2) The NODE 2 instruction is executed, & proper vectors & handlers (along with the EI instruction) are loaded in..."

So there it is. ZX84/TS1000 users with the Video Project ld take note of the COMPUTUS INTERRUPTUS series ኔሃ des irzozowski, in SINCUS ከ582, Although it’s 2068 oriented, this series gives a good insight into the use of interrupts, and is well written.

if you're a sericus 2X user, the thought of getting a disk interface must have crossed your aind at some point. You can pick up perfectly good (used) SSDD floppy drives these days for 490.00 or less, and new slimline 0300 drives can often be had for under $167.00. Cases, often with power supplies intact, can be picked up at ridiculously cheap prices droo several surplus parts suppliers.

1 recently picked up a used TEAC drive with supply, and decided to take the plunge. LARREEN:

1 promptly phoned Larken, only to find that while the 2068 version is indeed available froa stock, the 749i version has not yet been completely debugged. It could be ready in a few weeks, or months. If you send a stamped SAE to Larken, they'll notify you when the ZX version 15 ready to deliver. It stands as the least expensive disk cantraller being offered for the ፲1- when it becomes available!

A couple of years ago, AERCO was advertising a “full-blown P/M 2.2" for the 23, In wy conversation with Jerry, I asked ñ what ever happened ta this. dis answer, in a nutshell, was es, the CP/M setup dogs exist, and is available if you want t. However, it was considered impractical because very little CP/M software could be run ዕበ the 32-coluan screen.

Recently I have heard suggestions that st least one company was planning an 80-ር01, video card for the ZX just prior to the TIMEX dropout. If ANYONE has ANY into about an 90 col. video card that wight be married to the AERCU 2X-CF/M machine, please drop re a line and let me know.

Canada 57H 1፪1 aa has some incredible software available these days. Sinc-Artist 1.3 15 a program which 1 very similar to Zebra Systems’ Tech-Draw for the 204d, ፳-ስ lets you create pictures with 2544192 resolution, for output on a 2040 printer. The screen is a 48464 pixel windon on the hi-res picture, and scrolls around freely over the picture. The program has 40 different (redefinable) fill patterns, pencil and brush "draw" tades, a complete selection of shapes and filled shapes, including circles, rectangles, triangles, quadrilaterals} lines, rays, automatic horizontal or vertical area filling, and opaque or transparent draw modes. The picture can be printed cut as normal COPY size, or in 4 strips which make a 11,312" poster. The program has a friendly, interactive aenu system, and is written completely in machine code. Pictures . can be SAVEG.

Micra Drive

I would have to say that the AX J Micro Drive is basically a very fast cassette and does*t really approximate a disc operatig system. My reason for this 35 quite clear when I examined the commands

available. These commands are:




SAVE " "CODE S.L LOAD "CODE 5,L SAVE " "SCREENS LOAD "SCREENS These iagok remarkably similar to the commands for using a cassette recorder. However there are a few subtle differences. All blank micro cassettes must be formatted before beig used. This is accomplished by using the command SAVE *" i, +". Now the micro cassette is ready for use.

The FORMAT command does not work.

In the process of saving the symbol " " must be included in the save name in order to flag the micro drive, followed by the file number (what order on the tape it is saved) (1-9) and then followed by the name you choose. this means then that the operation of the micro drive requires that 3 characters be included in the save name so that the actual name can ጋበ1ሃ letters unlike the cassette save which allows a maximun of 10 characters in the save name. With a disc operating system there is a CAT function to heip keep track of the files written on the disk but this micro drive does not offer this luxury. The user is forced to remember or personally record the file number of each item so that you don*t accidentily write into an area that is already occupied. Also we are never realy sure of how many bytes of storage are free on the cassette and atten I nave tried to write more an the tape than it could hold causing an END OF FILE error message to appear. i

have 7

save is a file. For instace this (Tasword II) requires two be saved; ane for the basic

Each program files to

and one for the machine cod part. In order to save a file of tex! on the same micro cassette that the Tasword is on the command would br SAVE n Sy anyname" (of course without spaces in the save name whict included only to improve legibility. As another example the Program vuSd requires 4 files ta tr saved.


When your using the micro drive yo are not limited to 9 files per ጠ3ርሆር cassette. The manufacturer states that after ? a tenth file can ከዩ ranked using the symbol that follows in the ASCI code and that would be MaM Presumably an eleventh file could be saved by using the next symbol to follow in order which woulc be "3", however I have never had this many files on one cassette so whether it works or not is purely conjecture. In order to ioad, the load name only has to contai the " symbol and the name: the file number is nat necessery for loading.

Similar to a standard cassette there is a write project tab on each micro cassette which if broken off can be easily simulated with a piece of tape. One point of caution worthy of mentioning is that much care has ta be used wen inserting these micro cassettes as it is difficult to tell when they are properly in place. I have already carelessly wasted one 328 cassette as it began unraveling inside the drive. Fortunately I shut it down before any damage was done but I could not salvage the tape. The micro cassettes come in S lengths: Lentgh.. .(feet)..Capacity (kbyt) iG i4

Up toa this point I have not discussed the overall advantage of this over the stadard cassette, I have tabulated the results of same loading times for various programs.

I have found the micro file very user friendly for the limited amount it will do. The necessary conversions in the basic programs to use the micro drive with programs that run automatically are as elementary as using the stadard cassette.

The unit that I purchased was from FHEONI X ENTERPRISES in Dover, Delaware for a price of $231.00 Cdn. not counting the 104 import duty. Included was the interface, the drive, six microcassettes of various Sizes and a holder which is really a filer for business cards but the cassettes fit in it neatly. Although nothing is wrong with the unit itself 1. have had some other items prepaid and on back-order since January and not yet shipped. Due to an anwillingness of this company to refund my money oar even communicate with me about this problem I cannot reccomend them to anyone but Commodore 64 users.

The interface allows a second drive selling for $99 US which can be activated by poking 1 into address 24201. Poking Q into the same address returns interface to control of the first drive. Coming off the interface is a printer part that I haven’t explored yet but the printer cable and softwere are $49.50 US from the

manufacturer. Also SUN-WGRE sells the 8SK cassettes for $4 US.

note I would like to add seen the ROTRONICS WAFA Tt costs #319 Cdn,

duty, from DANCO and has 2 drives, a serial and parallel port and it comes with Spectral Writer and

an OMI-EMU cartridge ante a

that slides into the Port of the 2068 to turn it Spectrums This drive does behave more like a disk in that there is a CAT function that keeps tab of what is on the tape. The WAFA DRIVE uses the exact same micro cartridges as the A&J drive but there is greater storage capacity: instead of 85k the max is 128K. the drawback is that the WAFA DRIVE reads slower. Also I’m not sure about changing my main mode of Operation into Spectrum in order ta use the WAFA DRIVE. We could not load Tasman II with the OMI-EMU in place which is really irrelevant since the

Spectral Writer is a superior word Processor. For now Ill stick with Yankee ingenuity and Products

The 7040 Printer Interface a short lesson in decoding by Cameron Hayne

I/O port

Inside the funny shaped black box at the end of the’printer cable, the one you plug into your computer, isa circuit board with a capacitor, two ferrite rods and a chip. The purpose of the capacitor and the rodsis to reduce the effects of electronic noise. The purpose of the chip, a’ 74LSI10N triple 5።”3 በፀህቲ NAND gate, is to deliver a "pay attention” signal to the printer to tell it when the

computer is talking to it.

Most edge 2040

of the signals from the computer connector are not used by the printer but pass straight through the black box to be available for other, more demanding periferals such as memory expansion.

The connections and logic diagram for the chip is shown in Figure i.

A NAND gate has an output voltage close to 5 voits (high) except if all of aitsinputs are at 5 volts. In the latter unanimous case the output voltage drops to near zero volts flow). Thus we see the black wire will usually be at = volts. Working backwards, from right to left, we see that the only way the black wire will go low is if simultaneously A7 is high and both Az and TORQ are low.

IORG, which stands for input/output request, wili only go low when the computer does an IN or ልበ OUT

The port number attached GUT instruction goes onto the address bus, thus determining the voltage of signals Az and Af’. High corresponds to the bit

instruction. to the IN or

being =i, low to the bit =O. What this ail means in the case of the 2040 printer is thatt the printer will respond to any port number that: has bit #7 =1 and bit #2 =O. Port. number = 177770? in binary, where the question marks can be either zero or one.


Timex-Sinclair designated port i: Hexadecimal ) which doe indeed have bit #7 =l and bit #2 =Q But the printer will respond to ይ. ether port numbers as well not very desireable situation since othe periferals may try to use thos: ports.

Well friends as you have probably read my thoughts, that is precisely

what I did! The magic of electronic mail and telecomputing has come into my and many thousands of other computerist’s homes. With the addition of a modem weighing in at

less than a pound I have plugged into a world of information and resources so vast and accesible that one’s head whirls with the knowledge that sci-fi is here at ጠሃ fingertips. With the ease of picking up the phone I can call my friend David and send him a full computer program with all the trimmings. The program can have just a BASIC listing, or be written completely in Assembly or it may nat be a program at all. This very article which you are now reading was been wired between our computers via Ma Beli*s express for additions and editing on our respective TASWORD II wordprocessers-.

Let us not stop there. If that was all it did then I"`d admit that it was not as revolutionary as it is. Now how about this. have a question about how to set up my printer for

use with my computer. My Toronto associates are not aware of the answer. I think how nice it would be to send my problems out into the world where someane might know the solution. Again the solution is just., a call away. I connect with

I should explain that the modem can be used quite effectively with the software that comes with it (MTERM I). However using MTERM I your computer becomes a "dumb terminal”. This means that you can communicate with any board or computer with your modem but you cannot upload (transmit informatian) or download (save received information), A TS 2050 modem without MTERM II smart software is like owning a fine automobile with no licence plates...limited in its use! MTERM II also provides a
