Sinclair ZX80 questions

Hi, Jules Richardson said: I never had any problems with my Mk14 (which I've still got and it still works), an issue 2 board. The keypad was trouble right from the start and was immediately replaced with a modified telephone one, and it's worked fine ever since. The cassete interface, however, was a different matter, it would shed print if you just looked at it funny with a soldering iron. Like all Sinclair gear, designed down to a price - and then some! I'm afraid I seem to have lost my homebrew inout relay board and sound interface, but I think I've got the schematic somewhere... I also have a ZX81, but the only Sinclair bit left is the main board/ processor etc. Even the ROM has been changed, and it's in a large metal box with a 16K rampack, 2 inout boards and an 8 channel A2d card. Ah, the good old days... -- Cheers, Stan Barr stanb at dial.pipex.com The future was never like this!
