Hi,
I am currently restoring and upgrading my portable III 286. The machine generally work's but while I added a gotek and wanted to measure some signals i slipped and shortened the 5V rail. That caused the portable to reset and blew one of the fuses on the motherboard. That was pretty stupid of me. After that the system still boots up but the 5V rail now carries 7.5V. i am not really sure if that was before as well but it can't be healthy for the CPU and other components. So i don't want to turn it on again until I have that fixed sadly my knowledge about power supply's is rather limited. I opened the power supply I couldn't see any obvious issues...
Anybody has a clue what I could do?
