ZX80 Slow mode mod
Posted: Sun Oct 01, 2017 5:05 pm
Hello everyone.
I am new to this forum and this is my first post, I have owned and still got a ZX80 since it was introduced back in the 80s, I upgraded the Rom to ZX81 and installed an interface card to give slow mode, then it lay in a box for the next 30 or so years, I have recently converted it my ZX80 back to original by removing all mods, the question I have is related to the slow mode interface, I want to keep the interface card but it’s not complete having lost an IC, I was wondering if anyone has any info on this card as any info I had has long since disappeared, it would be nice to restore the card as a part of ZX80 history.
Any info would be much appreciated.
