I don't think writing SIMH device emulators for things like the DEC Unibus D/A
and A/D devices, or the DR11-A, would be at all hard.
Neat idea, actually. It would let me run the "LABBASIC" I created as an honors
project in college in 1974 -- a version of RT11 BASIC with added statements to
drive those data acquisition devices and the KW-11/P programmable clock.
