the same module as an 11/83 CPU card. They're both the KDJ11-B

When plugged into an 11/84 system, the KDJ11-B does NOT use Qbus.
It uses a unique bus that is similar to Qbus, but has some
significant differences. Also, the PMI (Private Memory Interconnect
on the C/D edge connectors) in an 11/84 behaves a little differently
than the PMI in an 11/83.
Looks like I got my information wrong or something... Anyhow, so can the
M8190 act as either an 11/83 (QBUS) or 11/84 (UNIBUS-ish) cpu? If so,
the FIELD GUIDE should probably still be updated to indicate this,
IMHO.
