Huh? Is the CPU chip on an 11/53 card an F-11? If so, is it the same
speed as an 11/23? I have 11/23 dual-height CPUs, 11/23+ quad-height
CPUs, but no 11/53 (nor 11/73) CPUs. I did see one about 11 years ago
as I was trying not to see it on my way out the door to start my two week
camping vacation. It was quad-height with some quantity of RAM on it
(1Mb? 1.5Mb?) The worst part about that experience is that the boss was
trying to leave, too; and it was a disk replacement job on a MUMPS box. :-P

IIRC, there is no MSCP support in 2.9. I have it (from waaay back, not
via PUPS) and ISTR having to load it onto RL drives, RK drives or RP
drives (or third-party XP (SMD) drives). I forget about 2.10BSD. I'm
certain that 2.11BSD supports MSCP, but might not be so happy on an 11/23
unless you've got at least 1 Meg.
