Code can be executed from the MMU PAR registers on
processors with
22-bit addressing (11/23, 11/24, 11/44, 11/70, and J-11 based systems).
My QBUS machine is apart at the moment, so I can't verify this before
posting, but I don't think this hack works on the J-11 machines; I
documented this behaviour here:
http://gunkies.org/wiki/KDJ11_CPUs#Code_in_PARs
It does work with F-11 processors (/23, etc). Not sure about model A
F-11's, which only have 18-bit QBUS addressing.
