The second memory boards CSR should be viable in ODT.
The toggle switch internal contacts may be tarnished with age. Cycle
each switch, that is used in the on position, multiple times and see if
the CSR appears.
Try another CSR if necessary to confirm the memory board is responsive
to Q-bus requests.
Which memory board and rev? MSV11-JE (M8637-E)?

Well, I was finally able to get a PMI memory board to
expand my
11/93 to the full 4 Meg. (Thanks Paul!)
I thought it would be as simple as configuring what bank I wanted
it to fill and inserting it (in front of the CPU). Sadly, that
didn't work. First problem is the only document i could find is
not for the actual version of the board I have. It has the same
switch sets so I tried it anyway. Set it to be in the upper 2Meg
and gave it the next CSR after the on board memory. No luck.
11/93 still reports 1024KWords and the Map command shows neither
the additional memory or the second memory CSR.
Anybody have any experience with this? Is there a switch I have to
change on the CPU module to make it recognize the additional external
memory? IS there something about PMI that I am missing?
Any advice gratefully appreciated.
