Default Re: Non-working Commodore PET 3016

As this is a 3016, some of the RAM sockets are likely to be empty even when the machine is fully working. If Colin can confirm his PCB is like the one in the image in #4, we can then explain how and where to measure the various supply rails and where to look for any critical ICs, such as the PROMs, which may be missing.
