Specs: Windows 10
I have a PCS 286 motherboard but I don't have any compatible PSU, so my plan is to modify one to get it working, but I need Olivetti PCS 286 pinout for doing that. Anyone can help?

Thanks in advance

✔ Best Answer
Oder PCs used the AT format so you're going to have to find an AT PSU with a hard-wired power switch. Do NOT attempt to modify or convert an ATX PSU.

It appears the PSU main power connector is proprietary. See these videos:

riider's correct about not trying to covert an ATX PSU, in fact, Olivetti was one of the "oddballs" in the 8088/80286 era (often using proprietary power supplies), so even a standard AT PSU may not work. Research all you can before attempting to replace the power supply...otherwise you may damage the machine beyond repair...

Strongly suggest you pose this question here (where a lot more people have experience with old Olivetti systems):

You'll need to register as well, and it may be a couple of days before you see your question post (new users are "quarantined" to provent spam; a practice I wish Computing.net would use)...
