Sinclair ZX80 / ZX81 Forums

Neazoi: hm, you are probably right. I first imagined that it really WAS a true ZX80/81, but they probably mean it is possible to switch ROM from 4k to 8k. So silly and dishonest to claim ZX81-compatibility :) Oh well, then I really MUST build an NMI-solution for the Minstrel I already have. Might s...

Neazoi: I was thinking about the ZX81-compatibility mainly. I'm sure the ZX80-parts are just plain copied from the original, but the NMI-circuitry has a few different implementation variants. Also, the switching between the ZX80- and ZX81-mode can possibly differ too. For example, a ZX81 in FAST mo...

Great to hear that you have one Jens! I have all the original docs and pieces, it's just not built yet. Do you have any comments on the compatibility of the ready-built computer? Any other opinions about it? I am really tempted to build it and try it out! Without seeing a closer photo, I believe it...

Press "M" this allows the block to move using the playing keys then press "M" again to give control back to the player.
You have to keep swapping between the two every time you want to move the block.

Great thanks!

I can't figure out how to make the 2nd level start on the darkstar2 flicker free game for the zx80. They say "space" is enough, but on the emulator the "door" doesn't seem to open to get the ball out and start playing on stage 2. It would be nice to know as this is one of the very few flicker-free g...

No but, I use V0.43 because it doesn't have the weird horizontal lines on zx80 and the screen is pure white as it should. BTW, I have decided to run my own programs archive for the machine, all copied from the web (your site and others) and scanned books/magazine issues. I made most of them availabl...

Here is the tool that should auto-detect ZX81 and ZX80 files (.p/.o/.80 etc) and convert to a sound file:

zx_p2wav_v0_04.zip

No this does not generate the correct wav files (zx80) wy the drag and drop option. However it works perfectly fine when it runs from the command line

Hi Guys, I'm currently working on a collection of ZX80 4K ROM games, some of which have been released through these forum but as this collection will be on real cassette any games publicly available will have extra features and/or improvements added. At least two of the games will be with my daught...
