Bill, Paul,
I have been tinkering with old versions of RSX11M (back to V2) on
non-mapped CPUs, primarily PDP-11/05 as I hope to get mine running soon. On Simh
with the CPU set as a PDP-11/05 which does not have EIS (I also tried an 11/40
but the SET CPU NOEIS in Simh gave me an error so I couldn't be sure if it was
disabled) I was able to boot the baseline distribution for RSX11M V4.0 on a
RL02 distribution. See details below on the config I tested. RSX11M is a pretty
capable multitasking, multiuser system and would be good fit for the PDP-11/40.
Best,
Mark
