BDV11 bootstrap-terminator/LTC. Most are 18-bit termination, but later

RLV12 - later version RL01/RL02 disk controller. Worth having.

These are a pair; the upper and lower parts of an RLV11 - earlier
RL01/RL02 disk controller.

terminal board?
Looks like the logic board from a VT100 series.

related to d2.jpg??
No, it's the main logic board from an RL01/RL02 disk drive. There were
three revisions, of which the first only worked with RL01s; this looks
like the second one.
http://www.classiccmp.org/acornia/ub/e1.jpg - 2x50W,
1x?? (I forgot to
make aaustinpass at gmail.com note). CU0210402 on the PCB, CS0110202 on the
"main" IC.
QBus 8-way serial line. Emulates a DHV11, IIRC.
http://www.classiccmp.org/acornia/ub/e2.jpg - 2x50W.
TC0210201 on the
"main" IC.
QBus tape controller, Pertec interface.
There were a couple of others too each with a 60-way
and pair of
26-way connectors; I suspect those are SMD.
Sounds very likely.
