Doesn't hurt, but if the sockets themselves are a problem, won't do much good.
Does anyone have a photo, PCB layout, or access to a
real board so that they
can check ROM chip locations for me?
Alas, no... there's a lot of stuff on zimmers.net (what was formerly
on funet.fi), but I no longer have a static PET... sold it years ago.
Date codes are all in 1978, so presumably I'm
looking at a first issue of the
ROMs?
I would say so. BASIC 2 for the newer PETs came out around 1978/1979,
ISTR; with the upgrade following on its heels. The only way to be
sure is the part numbers, though (which, I think, have already been
correctly identified by another list member).
