I repaired a DEC GAMMA-11 many years ago. The name comes from the fact
that it was used with a medical imaging camera (I assume using gamma
rays), the place I repaired it for was the vet. department of a university.
>From what I remember, it was a 11/34 processor with a VS60 grpahics board
set in it. It also had an RL11 linked to a couple of drives (that was the
bit I had to repair, sorry, so I didn't get to investigate any of the
'interesting' hardware). There was certainly a DW11 Unibus to Q-bus
interface, and some special Qbus cards to link to the camera. IIRC, there
awas a 5.25" BA11 with 2 4-slot hex backplanes in it, one Unibus, the
other Qbus. Confused me for a few minutes when I first saw it.
