That will definitely be entertaining.

It will need three PDP-8 fields just for the 41C ROMs (12Kx10), and
400 words for the basic 41C RAM (16 "status" registers, 64
data/program registers, all of 56 bits each).

I think the 41CX might not fit, because it would need six fields for
the 41CX ROMs, and 2320 words for the RAM (total 464x56). The
simulator code and OS/8 would have to fit in less than 1.5 fields.
