Well I'm hoping for the memory section that I can find at least one of the 4 core boards that works right away. I've got an 8k driver board I can swap it so I could run the system on only a single core board if needed. I'd probably write a short program to do a bunch of memory writes, reads, and

RE: HP 2100A Restoration

There is an HP book specifically on I/O interfacing to the 2100 (and 21MX) I/O bus. I think there's also an abbreviated chapter on it in a different manual. I'll see if I can dig up the name and if it's online anywhere. I've restored at least five 2100's, and run a dual cpu 2100A & 2100S
