Re: RF Video Distortion

Did you remember with newer ULA you need to twiddle the pots as detailed in the fitting doc?

Re: Query on a Issue 1 ZX81

That addon board is actually a rom patch and is detailed on these forums in another thread.

The bad news is your zxpand will not work quite right unless you remove the patch and change the rom chip :-( I have tried a zxpand on such a machine and it almost works but not quite.

Re: ZX80 Core - new ZX80 motherboards

Curses, v1.0b board was not as successful as the v1.1 build. Now onto the job of debugging what I got wrong. Will take me a bit as away on business next week!

Re: ZX80 Core - new ZX80 motherboards

40 SMD micro switches later and I now have the keyboard mounted on the zx80core.

Absolutely fantastic.

Re: ZX80 Core - new ZX80 motherboards

I am probably being really blind, but the Composite/Phono socket is missing from the parts list. I guess thats because it doesn't have a JXX number on the board.
