That's so bizarre (although the "Supermicrosystems Handbook", which covers
the 11/73, confirms it used the KDJ11-B). So the KDJ11-A (M8192) was not used
in any 'PDP-11/xx'?

The other thing that makes no sense is that the KDJ11-B (M8190) has all that
extra circuitry on it to support PMI, etc - all of which is unused in the
11/73 application! Why not just plug in a (presumably cheaper) M8192? In the
/73 application, the two are basically equivalent. (OK, there are two built in
serial lines on the M8190 - big whoop.) Both have 8KB caches (although the one
in the M8190 has slightly fancier tagging, IIRC), etc, etc. Maybe it's the ROM
(which the M8190 has, but not the M8192)?
