Hi all!
Thank you for allowing me to join your forum. I've lurked here for a while.
Back in the 80's I built a ZX81 from a kit. After some time using the built in keyboard I bought a surplus mechanical keyboard and rewired it for use with my ZX81. I used clear epoxy to glue on the keycap legends that I cut out of an advertisement. I also bought a floppy drive interface from Aerco.
Sadly after I got into IBM compatible PC's I gave my ZX81 system to the good will. (I will always regret that.) I also gave my home built 8008 away at the same time...
I am now trying to reconstruct my ZX81. I did find a FD-ZX floppy controller! Now I am looking for documentation. Can anyone help me out?
Cheers,
len

Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb

HI,
Still looking for a manual.
Also... When I pulled the EPROM to back it up on my controller it turned out to be blank. Might anyone have the firmware around for this controller?
