You are correct and that is what has happened, 9v on the 5v line. I did not realise CST put the link in.
JUst trying to ascertain what is damaged and what is not. So far 4 x DRAM and a 8049 destroyed, not checked
the 8302 yet. Once I know they are all working then I will move onto the logic......
PS. Forgot and a Minerva ROM damaged.....
They lift the BK side of L5 and then connect a large 2W resistor between that and the 12v supply at IC37 o/p
Getting to be an expensive learning curve. But I will get there..
A place to discuss general QL issues.
