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

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.
. No idea if it has additional logic on it or not.
An easier route might be to throw an FPGA on a dual height Q-Bus card
and reproduce the thing.

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
