And adding I/O to the /37 is hard -- there are five

CPU, memory, ATP/M (serial I/O), and GIC (HP-IB) you're already using
at least four. The fifth slot is often occupied by more memory or
something else (e.g. an INP or LANIC). I think there's a way to add a
second card cage to a /37 but I'm not sure I've ever seen that done.
My /37 is actually a Micro3000XE; two 3000 cages wired together
(internally at the backplane).
