So I'm trying to fix my old blown X68k PRO HD PSU to have as a spare after I did the ATX mod. I've got it to a point where the +5v soft power is working and I get a little fan movement when I plug it in. I was wondering if there is anything special to turning it on in the logic. It just sends +5v to the Power On pin, yeah? I don't get anything happening with that.
I couldn't find a datasheet for the PSU controller IC package, it is a NMB HS1049.
