Re: Spectrum+ 128k repair help (No CPU clock signal from working ULA)

Check that the 1K pullup resistor on the ula's clock pin output is present on the Speccy motherboard - SLAM needs it but it has been known to be omitted on some toastracks.

Re: Ron Bissell - I am looking for he.

Hi Jessica, Thank you for the speedy response - I am sorry to hear of your news. Your father's contribution to the ZX80 and ZX81 were true innovations in the early days of computing and transformed the expectations of many a home computer user. I remember the first time that I saw hi-res computer ga...

Re: SZ81 compiled for intel Mac OS-X

Re: My zx80/zx81 clon is working

Looks nice - although anyone else spotted there is only one W button (it is upside down!) and 2 rivets used instead of the other 2 W buttons....

Re: Issue 1 vs Issue 2 ZX80 case

Excellent although is it the angle of the camera - the front right corner looks different to the front left...

Re: MEMOTECH

Yes, a keyboard interface is one of the most popular wishes. A centronics interface is also a potential thanks to the Retro-Printer - however, it would probably make more sense here to develop a simple centronics interface which would work with the ZX81 and ZX Spectrum and just emulate the ZX Printe...
