I did once repair a GAMMA-11 system that was still in use (in a vet
(animal medicine) department). The problem was with the RL11 controller,
so I didn't have to investigate any of the odd stuff. I do rememebr there
bign both Unibus and Qbus boards in it, with a DW11B linking the latter
to the CPU's unibus. One of the expansion boxes had both Unbius and Qbus
backplanes in it...
Anyway, the OS seemed to be RT11. There must have been speacial drivers,
and control progrmas for the system. But I am almost sure it was built on
top of a nroaml RT11 system.
