I have one UC07. It is a dual-height board for QBUS.
I am planning to install that board in my 11/03.
Neat!
The UC17 is a quad-width Unibus board that is half-populated with
components, to make a single SCSI host adapter. The UC18 is the same
thing, but with all component positions populated. Very odd.

Uh, UC07s are UNIBUS, not QBUS. I've got a UC08, the dual-SCSI port
version of that.
No, they're definitely QBus, as is UC08. They're both quad-height
cards, at least the ones I've come across, but I believe there was a
later dual-height version with the same designation. I don't have
one
but they're listed in lots of places and I know they work in
microVaxen
as well as PDP-11s. UC17 and UC18 are Unibus, I believe.
