So the quick answer is probably that all M8190 boards are PMI capable, but
the PMI is not activated if PMI memory is not present in the correct
slot(s).
In addition, probably all M8190 boards are happy being placed into a VT103
backplane which will not support PMI activation.
Of course, I can't guarantee there won't be magic smoke released if the
M8190-AE
is placed into a VT103 backplane.
I remain skeptical that everything will just be fine if you place an
M8190 KDJ11-B into a non-Q22/CD backplane.
If you look at Table 2-9 (page 2-19) and Table 2-10 (page 2-20) in
EK-KDJ1B-UG_KDJ11-B_Nov86.pdf, won't placing an M8190 into a
non-C22/CD backplane essentially connect the CA1-CV1 signals in Table
2-10 straight through to the AA1-AV1 signals in Table 2-9, and same
with the DA1-DV1 signals and the BA1-BV1 signals? That doesn't seem
like something that would allow normal functioning.
Also, it is clear from Table 2-10 that the PMI signals on the M8190
only exist on the top (component) side of the board and can only
communicate over the PMI with memory boards physically located above
the M8190.
