BDV11 bootstrap-terminator/LTC. Most are 18-bit termination, but later ones - or with a trivial ECO - are 22-bit termination.

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.

Looks like the logic board from a VT100 series.
http://www.classiccmp.org/acornia/ub/d3.jpg - 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 [email protected] 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. -- Pete Pete Turnbull
