Were you looking to buy a RKV11-D?

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

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 my industrial-grade
scanner at its highest resolution; no

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
Would anyone know whether there is a backplane wire list diagram anywhere for
the RKV11-D Qbus RK05 controller
like the one on eBay a few days ago?
I didn't get that one but I have a pair of NOS H803 4x dual-height socket
blocks kicking around that I guess
could be wire wrapped into a replica RK
