ZX81 BASIC Programming Book

[Lardo Boffin]

And

[David G]

Thank you. I had the smaller version, also spiral-bound but with a plastic spiral

I see what the problem is with Appendix A. Character 135 is showing the ZX80 character, not the ZX81 character. The folding Reference Card shows both

Thanks Mark.

Where did you see the printer’s information in the First Edition? I couldn't find it.

On the last page (page 212) at the bottom.

Page 212 of ZX81 manual (first edition)

Interesting!

None of my four have that printed on page 212.

I assume there must have been at least two print runs of this edition then.

I assume there must have been at least two print runs of this edition then.

By two different printing companies maybe

I just got another First Edition today and it has got the Leagrave Press info on page 212.

Either they didn’t put their name in to start with or it was two companies. Guess we will never know.

So I now have:

Spiral bound -
4 * First edition from 6 King’s Parade - no obvious mention of who printed them
1 * First Edition from 6 King’s Parade - printed at The Leagrave Press
1 * Second Edition 1981 from 6 King’s Parade - printed at The Leagrave Press
3 * Second Edition Reprinted 1982 from 6 King’s Parade - printed at The Leagrave Press

Perfect bound -
1 * Second Edition Reprinted 1982 (212 pages) from 25 Willis Road - printed at The Leagrave Press
3 * Second Edition Reprinted 1983 (160 pages) from 25 Willis Road - printed by Richard Clay Ltd

Leagrave press was dissolved on the 9th of this month.

During WW2 it was the production and packing facility of the S.O.E ( Special Operations Executive ) print works apparently.

Richard Clay limited looks like a company with origins in the 1700's

Here is another edition, in French with two different 1st Edition printings

ZX81 BASIC Cours de progammation par Steven vickers



PDF (two different ones) 212 pages

First one, from the inside page:

1re Edition 1980
(C) 1980 par Sinclair Research

Back cover:

DIRECO INTERNATIONAL
30, avenue de Messine
75008 Paris

IMP. AGGATOR PARIS (1) 222 60 20

Is that abbreviation for "imprimatur"?

I think DIreco International is/was a Singapore import/export company with offices in Paris and New Jersey


The second PDF is, from the inside page:

1re Edition
1980 par Sinclair Research

lllustration de la couverture réalisée Dar John Harris à
l' intention de Sinclair

Both printings have the correct CHR 135 graphic (page 184), unlike the English Edition 1


And, a spiral-bound version on eBay

Just look at that John Harris illustration. It's like two spaceships on top of building in a TRON-like city of computer chips

"Direco" was a distributor and publisher of programs in France. Main Sinclair importer, it distributed ZX81 but also hardware such as Memotech,AGB cards, software translated into French such as ARTIC Assembler or "3D Monster" (translated "tyrannosaure Rex"), "Othello"...








Direco also published a magazine to sell or promote there hardwares/softwares: (Dir'Echos Sinclair)

This book was released to be distribute with their ZX81 package (a ZX81, a keyboard and two 1k tapes)

Excellent information, thank you
