Well, I tried the next steps, with my limited
equipment, and no joy.
Here's what I've tried so far,
Possible reset fault? Check connections to display logic too (PIA /
6520 / U1) - pin 1 is ground, 22, 22 and 24 should be at +5V. Pin 11 is
clock, and pin 8 is the same reset line as for the CPU.
I've got the schematic - it's around the size of 6 sheets of A4 so could
just about scan it if you want (and can't find it on the web already).
