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.
