Re: SZ81 compiled for intel Mac OS-X

I will repost the screen shots soon when I can figure out where to store them. Linking them from Google Drive did not work and there doesn't seem to be a way to upload images to the forum.

Re: My zx80/zx81 clon is working

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...
