They are marked 2102A
Indeed... 8212
Eproms or PROMS? They're marked C1702A
Now is a good time to ask the list for advice on what to do BEFORE applying
any power to this machine. I consider this one quite historical, and don't
want to any damage. What are the things I should check?
Cheers

2102s are 1Kbit x 1 static RAMS, the memory of choice in the 70's, power
hungry but easy to design with. An Intel 8212 is an 8 bit latch (should be
a 24 pin DIP), commonly used on 8080 boards to latch some control signals.
1702s are 256 x 8 (2Kbit) EPROMs, a real pain to program, that's probably
where your boot code is.
