Yes, it does help. There are 3 issues that I am trying to resolve:
1. Running in 32kb of memory. If I use the 32kb MXV11 can I run RT11
V5.3?
If it works in SIM

No, it'll take a NXM trap (through 4); what happens then depends on what the
trap handler is set to - if anything.

You could do what I did in the box I have for running LSI-11's in: when I
upgraded the backplane from Q18 to Q22, I put in a 4-switch DIP pack, and ran

I had really hoped to be able to put together a simple system to
demonstrate the difference

I have the DEC cards, but I think that box had a 4 x 4 backplane and came
with 16 bit addressing (M7264) and could be upgraded to 18. I'm out of
town so I can't really check. You might need a BA11-N, S, or BA23 box to
support the Emulex controller.
The Q-bus backplanes can be confusing and I don'
I have a BA11-M box with a backplane that I am sure has been upgraded to
be 22 bit addressing.
When I got this box it had an 11/23 Dual width Cpu, MXV11-AC with custom
boot ROMs and a 256KB MSV11-P memory board. The memory in the MXV11 had
been disabled so I suspect the backplane was upgraded
