The major groupings you can do with the PDP-11 systems
are otherwise if
they have split I/D space, supervisor mode, unibus map and 22-bit
addressing, floating point (none/FIS/FPP) and EIS.
Rougly, you can say:
11/34: EIS. Optional FPP.
11/40: None of that. Optional EIS and FIS.
11/44: All of it. Optional FPP.
11/45: split I/D, supervisor, EIS. Optional FPP.
11/60: EIS. Optional FPP.
11/70: All of it. Optional FPP
And let's not forget the CIS Option. :-)
