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). --Chuck
