Hi JG,
Thanks for your message.
I suspect that the fault lies with the FDD/Interface because of the lack of the 5 Volt rail.
As everything else on the CPU board seems to work well it is as you say unlikely to be on that board.
I did a basic machine code / robotics course in the early eighties but I have forgotten most of the useful stuff.
As my old boss used to say "there are no problems only solutions".
Another check of the interface board for failed components.
