Another OS that would run on your machine (as
well as an 11/20) would
be RSTS-11 (V4, or I suppose V3 if you can find that)
I'd love to have an old RSTS-11, is there any variant around?
Yes, on bitsavers. But John's comment reminds me that RSTS-11 V4A doesn't
support RL02. (Only RF11, RK11, RP11.) V4B may be different, I don't know.
didn't use the MMU
Huh? He's got an MMU (I think): it's the EIS he's currently struggling
with.
True. I meant to point out the main difference between RSTS-11 and
RSTS/E. The other difference is that it doesn't require EIS. Both follow
from the fact it was designed for the 11/20.

So you're saying for a system with a MMU but no working EIS (removed for
now) and 64KW RAM (half populated M7891) you're suggesting which OS? I
still have to research the best options, RSX-11M?
I was able to get the extended three cables so I can put the M7238 EIS card
on a riser so I can probe for faults, and maybe if I am lucky boot XXDP+.
With the EIN installed I can't boot RT-11
