I highly doubt thats the issue - but hope it is

Regardless of what the issue is, the sockets should be replaced, as Studley says they are 35 years old (and not that good quality to start with).
You could go around in circles checking roms and whatever and all along it was the sockets that should've been replaced before even starting anyway.

So rectifier board now complete. Started pinning the wires into the plugs and realised that the J1 connector has two identical red wires and two identical yellow.

Does anyone have a pinout from the Molex square plug, back to the board J1 connector?

Spent the day up with Studley working on the MPU board.
We tested systematically, fixing problems we came across as we went but to no avail. Just couldnt get the board working, so after a day of trying, i decided to grab one of his spare Alltek MPU Boards.

I can't thank this guy enough for his afforts & troubles, a very friendly and helpful guy who wants to impart his knowledge to others - he even fed me lunch!

Thanks Damien!

Next - onto the solenoid board driver - some wierd AV voltages so will be replacing the large capacitors and any known bad transistors and working from there. This project has been a very good learning curve!
