Sinclair ZX80 / ZX81 / Z88 Forums

Thanks Mike! It's in times like these that I wish I knew machine code. I have ideas and I try to imagine how to do it, but I have to ask here and there and hope that I'll be able to get a result. I've contacted SpecAY's author and asked if he could give us his input and permission to use his code (i...

I started reading his old magazines last year and I will never forget what he wrote about still feeling young. In a certain way, we're all reliving our youth. I'm happy for Andrew and thankful for his work.

Thanks. I've started scanning Sync magazines, The Best of Sum, Powerful Projects for your TS2068/1000/1500 and now the articles on the Radio_Electronics magazine. It's going to take some time, but it will be done.

Thanks! I guess it's time to start looking for a list of clock frequencies and ports used on each board. Let me see what I can find.

Here in the U.S. little boards were sold to aid TS1000 users in loading their tape software. I have one that was made in Canada, but I think it's damaged. If a better quality picture is needed I will gladly provide it. I would like to know if it can be repaired or replicated. It may sound incredible...

It seems many, if not all of the sound interfaces for early Sinclair machines used a compatible chip with the one used on later 128K Spectrums. If this is the case, what would we need to play .AY files on a real ZX81 with one of these interfaces, or an emulated one? The program currently used to pla...

Thank you Mike. Here are some of the thinks that I really like about EightyOne: -TV emulation -Number of clones emulated -Number of peripherals emulated A few things that might be useful in the near future: -Option to load from audio source. I'm testing many TS1000 tapes and it would make the job a ...

I have a few american magazines with hardware projects for the TS1000. Is anyone interested in scans of these projects? Some of them might be incomplete (part 2 of 2, etc).

More info about the magazine can be found here:

That's right. I have a full backup (I think) of the whole ts1000.us site, made in April 2007. I had forgot about this backup until last night. My hosting space doesn't allow files bigger than 5MB and a torrent would be too slow, so I uploaded it to Megaupload. If you never had a chance to visit that...

Dunno if Rich would approve, but a logo for this forum would give it a better identity. Take for example http://www.speccy.org , which uses the same type of forum code. If Rich approves, and if enough users join, a competition could be held to see which logo would look better, and users who didn't p...
