Sinclair ZX80 / ZX81 / Z88 Forums

Hi. The coloured interferences are quite normal on LCD monitors. Mine does them as well. However I have almost no problem with it on ZX81, only when some "big" sync happens, for example when entering FAST command (and pressing keys). I have this problem also on Didaktik M 128K (a Speccy clone). I ha...

Hi, the Manic Miner is Czech work from 1984 and works with 16K. The game has about 11kB and contains only 11 caverns, instead of 20. The HRG is done by software trick, no extra add-on is needed. The game itself is also much faster than the Spectrum version and some details are different. I have it s...

Btw. does there exist any TV advert for ZX81? There's not so many of them for the Spectrum available on the internet, and I suppose there is nothing ever made for ZX81. But, the English people could know more

Yo! How is it possible this ZX-81 has rubber keyboard (looking like factory stuff, not "hand-made")? http://hooyprogram.republika.pl/zx81rubber.jpg http://hooyprogram.republika.pl/zx81rubber2.jpg http://hooyprogram.republika.pl/zx81rubber3.jpg (It's not mine, *SADLY*). Greetz, Yerz I think it's thi...

I think you probably don't know this video of Frantisek Fuka aka FUXOFT (famous Czech ZX Spectrum games programmer and film specialist - www.fuxoft.cz) from his childhood, filmed by CST in 1982 in some shot about computers and youth. At the beginning, he's writing some basic program on the ZX81 and ...

Superb game! Seriously, I think playable Doom won't fit into 1K, but something like 3D Monster Maze could.. In very very low-res.

Hi, these tricks are surely perfect, but when typing a prog on 1K machine you have to use regular numbers to get some memory for editing the prog. Also, using these tricks rapidly slows down the program's run. If typing something time depending (loops making screen effects or animations) it's better...

You could ask Czech/Slovak coders to join. ;) Btw, the funny thing is - ZX81 HAS beeper. :) http://zx81.republika.pl/beatles.p http://zx81.republika.pl/classik.p The problem is - its audio output seems to be weaker than on Spectrum, so for now I listenned to the tunes only on emulator. But try to c...

Btw. I've made some promo, so I hope someone else from CZ/SK could attend...

Well, first I wanted to make such a compo for JHCon Speccy party being held in December, but, why not this. I can make some more than JetSet Willy 1K of course :) I got a 16K RAMPACK yesterday - well I disconnect it :) Is Yerz's and Johny's work in the compo? Anyway, I think ZX81 is cool. It's so si...
