On a related note, what kind of documentation is out there for the
various oddball QBus to Unibus converters? I have at least two of the
Plessy models that came from the USPS project in the 80's (they used
pdp11/23 cpus in a Q bus backplane next to a Unibus backplane that had
all the X.25 comm

My fiche set has the Technical Manual, and also (in the wirelist
section) the wirelist.
Not sure how to get it to you, though. I stuck it in

It is a Qbus to Unibus converter.
Also, it is only 18 bits.
Yeah, info does seem to be scarce. Not even in my LEVAX fiche set.
But maybe decipherable? Since three of cards are the same (per the
Wiki), those interconnections would presumably be the same as the
RK11-D. That fourth card (M7268) is apparently a connector card for the
Q-Bus and drive bus. N
I've got a couple of Teac FD-54B's that appear to have problems with their
index sensors. Does anyone have any docs for these? The internet seems to
barely know they exist vs the FD-55, which has info everywhere. I'm thrown
off a bit by the 3 wire phototransistor (vs the common 2 wire ones) they
