UIEU FROM RANTOP

Hot much to report this month. Iam sad to say that another fine TINEXsinclair club has gone the way side. BoSTUG of The Boston Computer Society mailed out their last newsletter. They decided to break up the group for the same recsons any group would dispand. We gill surely miss them. Eight years ago Ba- STUG uas the major force in the establishment of the BCS accord— ing to Peter Hale, editor of the BoSTUG Neusletter. Feter states thet the GL users have started an independent Heu England Sinclair QL User Group CNES@LUG> that will continue support in the area and produce a quarterly neusletter at the same address as before vith a $10.00 annual fee for membership.

I have enclosed sy printed circuit board CAD progras for SHAREQAEE distribution throughout your wenbership groups and others. You be the judge about hoo an advanced application can be supported by the such saligned, but phoeniz-like the TIMEXsinclair 2068.

ChDS3 Bi sidesteps around TIMEX barriers Ghich sang deny exist. 811 1 can say is: “You sean I can't do THIS?". THIS is impressive!

Qhen I sade the BOM BYPASS and sisnle HENORY RANE SQITCHING public dosain, I included the design of the QIDJUF PRIMGBY ADAPTOR and a pro- posed standard for back-planes. This design coapletes the data required te add back-planes dand a1] the pouer that giges) to that inherently SUPERIOR computer,

Even vithout B&NR SQITCHING or IBM BUSS COMPATIBILITY, all existing harduare can be sisply adapted to plug in. Heo hardoare, like half aay decent parallel interfaces, can be nade bith tuo edges. One edge plugs in for the Binisus bus configuration -- the other for IBY compatibility oith BAHR SQITCHING. The adaptor is compatible uith existing hardoare, but nev products vould better be consistent vith the neo standard.

For those who have tight budgets (or fists), the entire ingesteent to implesent a back-plane is less than $90 for the sinisua configuration. That for IBM compatibility will be someohat sore, but the savings through the use of clone hoards wakes that trivial.

The buss driver card is the only ites not yet detailed. for the sinisus systes, ail the design data has already been given.

The figures shoe both of the PRIBABY SDAPTOR. These cere generated using CAD#3.B1 using PUBLIC DOQHSH data files donated in the interests of TSZ068 users every-

The first personal computer

for under

The Sinclair ZX80. A complete computer— only $199. 95 plus $5.00 shipping.

Now, for just $199.95, you can get a complete, powerful, full-function computer, matching or surpassing other personal computers costing several times more.

It’s the Sinclair ZX80. The computer that “Personal Computer World” gave 5 stars for ‘excellent value’

The ZX80 cuts away computer jargon and mystique. It takes you straight into BASIC, the most common, easy-to-use computer language.

You simply take it out of the box, con- nect it to your TY, and turnit on. Andif you want, you can use an ordinary cassette recorder to store programs. With the man- ual in your hand, you'll be running programs in an hour. Within a week, you'll be wnting complex programs with confidence.

All for under $200.

Sophisticated design makes the ZX80 easy to learn, easy to use.

We've packed the conventional computer onto fewer, more powerful LSI chips— including the Z80A microprocessor, the faster version of the famous Z80. This makes the ZX80 the world’s first truly port- able computer (6%2” x 84%" x 1%" and a mere 12 oz.). The ZX80 also features a touch sensitive, wipe-clean keyboard and a 32-character by 24-line display.

Yet, with all this power, the ZX80 is easy to use, even for beginners.

Your course in computing.

The ZX80 comes complete with its own 128-page guide to computing. The manual is perfect for both novice ang expert. For every chapter of theory, thdre’s a chapter of practice. So you learn by ¥omg—not just by reading. It makes learningteasy, exciting and enjoyable. -

You'll also receive a catalog packed With items that can make your ZX80 even more useful. Including 27 program cassettes, from games and home budgeting for just $6.95, to Sinclair's unique Computer Learning Lab (a workbook, six cassettes with 100 lessons, and two cassettes for storing programs).

ZX80’s advanced design features. Sinclair's 4K integer BASIC has perfor-

mance features you'd expect only on much

larger and more expensive computers.

@ Unique ‘one touch’ entry. Key words (RUN, PRINT, LIST, etc.) have their own single-key entry to reduce typing and save memory space.

$200.

@ Automatic error detection.

A cursor identifies errors

immediatély to prevent entering

programs with faults.

@ Powerful text editing facilities.

@ Also programmable in machine code.

@ Excellent string handling capability —up to 26 string variables of any length.

@ Graphics, with 22 standard symbols.

@ Built-in random number generator for games and simulations.

Sinclair’s BASIC places no arbitrary re- strictions on you—with many other flexible features, such as variable names of any length.

And the computer that can do soe much for you now will do even more in the fu- ture. Options will include expansion of 1K user memory to 16K, a plug-in 8K floating- point BASIC chip, applications software, and other penpherals.

Order your ZX80 now!

The ZX80 is available only by mail from Sinclair, a leading manufacturer of con- sumer electronics worldwide.

—,

Price includes TV and cassette connectors, AC adaptor, and 128-page manual.

All you need to use your ZX80 is a standard TV (color or black and white). The ZX80 comes complete with connectors that easily hook up to the antenna terminals of your TV. Also included is a connector for a portable cassette recorder, if you choose to store programs. (You use an ordinary blank cassette.)

The ZX80 is a family learning aid. Children 10 and above will quickiy understand the principles of computing—anc have fun learning.
