Chuck,
Yes, I mean Monitor II-D.
No, CHM does not have a working 1311 drive. The need for Monitor II-D
is for the IBM 1620 Model 2 simulators being written. Monitor I does not
run correctly on a 1620 Model 2 when index registers are enabled and
used by a program.
My recollection was that Monitor II-D was about a tray of cards to load
onto a 1311. It would be quite the tour de force if someone managed to
keep all those cards around.
Never had the pleasure of running a Model 2. All my experience was on
CADETs with options needed for Monitor II-D (and SPS and FORTRAN).
