The 11/73 is the one that's got the 15MHz CPU
and accesses memory
across the QBus, right?
Yes, except that quad-width 11/73 CPU boards (KDJ11B)
can use PMI
memory. Duals (KDJ11A) cannot. Also, earlier revs can't take an FPJ11
chip, but later ones can.

On that note does anyone have an extra they are looking to trade,
sell, or hand over the cost of shipping ? I have a microPDP 11/73 in
the original pedestal BA23 with no cards at all in it. Can it even be
called a 11/73 with no cards ? I guess what I have is a BA23 pedestal
with a cool MicroPDP 11/73 badge on it.
Piling onto this thread (sorry), I'd love to find a BA123 enclosure.
I've had this dream of building a "large" (for small values of large)
MicroVAX or LSI-11 system for awhile but one's never come my way; anyone
out there have one going spare?
Thanks,
