I agree with Herb on that. Part of what I like best about getting a new toy is the triage and discovery of the system.
If you suspect memory I would try to find a simple test program (if the system even allows you to get that far). As far as parts there are plenty of vintage chip suppliers out there.

Earl, I re-posted your request, to have an appropriate subject. Your
post was buried with a bunch of other postings. Myself, I like COSMAC
stuff, congrats on your find.
The VIP is popular among COSMAC (RCA 1802 processor) enthusiasts. You
will find other owners in the Yahoo cosmacelf discussion group.
Of course, spend time with what you got, and find out what's actually
going on with it. Then look for chips by model number to see if you can
find it or them. Much of the fun I have with this stuff, is in figuring
it out myself. But it's also fun to discuss repair and parts, once
details are established.
