Re: zx80 clone which is the best most accurate?

Is he the guy who did the Jupiter Ace kits? [see this thread].

If yes, then Phill (Prime) has. I have also.

Re: zx80 clone which is the best most accurate?

There is/was an exact copy of the PCB that was available. You can't get better compatibility than that! Have a look at Grant's wonderful site here ;-) In reality, the only difference between a modern clone of a ZX80 and the real thing, is the RAM will be a modern CMOS SRAM chip instead of the old 21...

Re: Sinclair ZX Spectrum - console + power supply

Do we need a backup copy of the full eBay site on this forum? What's next? A full copy of Google? On the Atari forums the moderators have to ‘release’ your first three posts - while this would be extra work for the mods (not something I would wish upon anyone) it would help prevent those who only w...

Re: Sinclair ZX Spectrum - console + power supply

The eBay vender is a commercial business. Hence I would expect a fully working ZX Spectrum to be fairly high compared to the typical eBay prices of a working ZX Spectrum.

Re: ZX81CCP

Hi Ben Now that is a question that I don't know the answer to. The basic version (ZX8-CCP) without fast mode sync definitely works on a U.K. / European ZX80. As I have fitted one inside the modulator for RWAP on the ZX80 he had. As the video signal from a ZX80 is a monochrome composite signal, I can...

Re: WHSMITH Computer Program Data Recorder

This " cassette deck with computer setting" came up on WoSf a few years ago. I don't think / can't remember if it was that model though (WH Smith just "badged" and sold these, they were available with other brand names). Alas, I can't remember the outcome. A member was going to post up details... Ma...

Re: Improving Timex/Sinclair Tape Loading

Yeah, I've been distracted with other things.

Hopefully at the weekend, I can do some more. I'll then post an update here.

What floppy disk drive system do you own AND use on your ZX Spectrum or compatible computer?

What floppy disk drive system do you own AND use on your ZX Spectrum or compatible computer? By use, I mean you actually use it regularly (more than twice a month) or occasionally (more than six times a year). Not that you have one and have used it a few times when it was new to you . I've listed th...
