I have a Tempest here that until recently was working fine. It seems to boot okay but if I put it in self test it won't even pass the first ram test. The manual indicates that if it stays on the first one that is the Vector ROM at N/P3. That's fairly clear, and these issues are normally sockets, so I swapped out that socket. No change with the new socket, same error, same boot behaviour.

I'm assuming the next step is to swap out those two Vector ROM chips. Does anyone know of a good source? I'm trying with HobbyROMs but he doesn't seem to know what I'm talking about.
