Re: Non-working Commodore PET 3016
It is odd that the -5v is measuring so accurate as -12v, I’d agree with Sirius to check the markings on the device, but maybe also take a close look to see if it might have been changed at some point. Look for signs of hand soldering or post a close up of the back of the board.
Edit: just saw colin’s reply, so looks like -5v supply is ok after all.
