The really odd thing, is that SirMorris tried the two ROMs sent back to him in his ZX80 and they both worked...... :?

I wonder if SirMorris can spot the difference?

As far as I know my ROMs did work in Charlie´s repro machine, but he wanted to test it also on a real ZX80.

Ah I didn't know his was a repro, I know he's re-flashing some before sending them to me but I don't mind testing some suspect ones in mine as well to try and determine what's going on

As obviously I am the only one so far where the ROM was not working, I guess it might have to do something with my ZX80 version. But whatever, I am happy that also the ZXpand works fine now on my ZX80. :)

Paul´s Mazogs port for the ZX80 is really impressive! :D

That Mazogs port looks amazing, shame my LCD doesn't seem to like the "flicker free" signals from the ZX80 so I might have to get out my gaming TV again (found it in a skip haha)
