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.
I am mostly in "acquisition mode" nowadays, but I do have lots (and
lots, and lots) of DEC boards. I can probably swap you a CPU at least.
Whatcha got to swap?
