Did you have a joystick or RAM expansion on the back by any chance?
Basically the edge connector was not sufficiently protected and a loose connection could fry the ULA or other components quite easily.
- bartread 8y agoYeah: Kempston joystick port plugged into the back. I also had a light pen that had a separate adapter so there was some swapping around from time to time. Always with the computer switched off, mind. Loose connections on one of the adapters might explain it. Not sure what the problem with the +2A would have been though, because it had proper joystick ports, and I'd stopped using the light pen by then.
