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. Good luck!

I got one of these (https://www.youtube.com/watch?v=IkgmAjE1ONY) arrived last night... With original box, manuals and even sales receipt!
[video shows an RCA COSMAC VIP single-board computer. Unknown if the items shown match what Earl obtained.]
There may be a bad RAM chip... (according to the notes on the box...) Any ideas if I'll have trouble finding an appropriate part to fix it? (I've only had time to unbox it, not look thru the manuals or anything but thought I'd try to tap the collective intellect here to get some initial thoughts..)

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. Herb Johnson -- Herbert R.
