Hi
I've recently collected a November 1984 IBM 5150 with Floppy, HDD, CGA & colour monitor but it won't power up.
I've removed each of the cards in turn and after removing the serial/parallel controller, the HDD span up but I didn't have the CGA card in to see what was happening onscreen. On replacing the graphics card, the machine refused to spin up again. I've since removed all the cards apart from the graphics card and disconnected the power connectors from the Floppy/HDD but I still get nothing.
The 5150 has apparently sat unused for over 2 years in a kitchen and was sold as working.
Tonight, I thought I'd check the voltages on the PSU and the most it outputs is 0.039v!
I'm glad it looks like a PSU fault - I should be able to get this repaired.
I'm not qualified to go poking around inside 240v mains powered PSUs, so wanted to ask if anyone knew someone or somewhere in the UK qualified to repair mine?
Regards
Mark
