Sinclair ZX80 / ZX81 / Z88 Forums

Ah cheers again - I guess pokemon clinches it - can't be clearer than that!

Hi all, There was a very famous program in the 80s - so famous I can't remember the name. It was like Life, Sim or Nim even. The ZX81 version on start up showed a few apparently random dots on screen. As the situation (habitat? world?) evolved the dots became less random and "evolved" into patterns ...

Thanks good people! and hi moggy, well yes treat the zx to a few gb...are there enough progs in the world to fill it though??!! Ebay, Phil yes, hadn't thought of that. Andy, well I saw a 128 GB SD on amazon, but not a MB - maybe I missed it, I'll have another look. I'm using a 1gb at the moment whic...

Hi all,
Does anyone know anywhere to get new SD cards @ 64, 128 mb etc. ? I tried amazon with unsatisfactory results. Even my local Asda don't do anything lower than 4 gig now. I don't want my ZX81 to get agoraphobia...

Big cheers everyone, that has been a very enlightening discussion! It looks like identification requires some hands on inspection - at least to the underside of the expansion port. I thought there might be some obvious external marker, but anyways, a very educational outcome for me! Thanks again Pro...

hi All,

Just a quickie - I was wondering how to tell the difference between zx81 versions simply on opening the box - I've no idea which series mine is and only realised there were differences from this site!

cheers

I borrowed a few gold trs connectors from some audio stuff and put my tapes through at near top volume and have had 85% success rate with t...

Hi Paul and Sirmorris, Many thanks both for those replies! Sounds obvious now you say it - so "MinesofSaturn" won't do! Can't wait to give it go. I will report back. Mind you I recall having a good few programs on tape with long REM titles often containing notes and/or descriptions. I presume it sho...

Hi all, I am enjoying the zx81/zxpand - but would get a great deal more out of it if I could access .p downloaded files; and also had a reliable cassette machine! 1. I have downloaded .p files but when transferred to the zxpand get altered filenames e.g zxchessII.p becomes zxches?1.p . They appear o...

Thank you yet again Moggy! And for the welcome. I hadn't seen that site for Chris Bidmead, but he's obviously a man to know. Funny, he lists PC/M but I was sure the stuff I saw was in ECM - have to look again. I went on ebay and was very DEPRESSED to see these mags on starting bids of 9.95 each with...
