Nice system; the CPU has the MMU and FPP
And it's a Rev.D (you can tell from the jumper layout), so full 22-bit.
you've got what's probably a 256KB
memory card (an NS23M - documentation is available - depending on the chips,
it can be 64KB or 256KB - if the former, let me know, I'll swap you a 256KB
one)
It has 4 x 9 x 4164s, so it's 256KB with parity.
and I think the pair of quad cards are probably an RLV11.
Yes, they're an RLV11.
