Hi everyone,
Being personally quite interested in DEC's laboratory systems, I
stumbled a few days ago upon some scant details on DEC's nuclear medical
imaging system, the Gamma-11. Apparently this PDP-11 was designed to be
connected to a Gamma Camera, and had a VT11 or VSV11 display system
connected to it. As well, along with it came a modified version of
RT-11.
I was wondering if anyone on the list had one of these machines and knew
what parts made the hardware a Gamma-11, as well if anyone had manuals
I don't have one, but I did repair one about 10 years ago (it was still
being used for 'real' work back then), so I have some idea as to what was
inside. I never worked on the camera side of things, so I can't comment
on that.
The machine consisted of a normal 11/34 processor (I can't rememebr if
there was a floating point oard in it or not) with a grpahics display
system, I think it was a VS60. There was an RL11 disk controller linked
to (IIRC) a single RL01 drive.
There was also a 5.25" high expanison box. This contains 2 4-slot
backplanee. One was Unibus, linked to the 11/34 Unius, and contains (IIRC
again) the RL11 and the Unibus end of a DW11-B. The other was Q-bus, and
contains the other end of the DW11-B. It also contained 3 special Qbus
cards which were the interface to the camera. I probably took copies of
the printsets for those, but don't expect me to find them in the near future.
The only part I had to repair was the RL11, that was standard. So alas I
didn't get to look at any of the 'interesting' bits.
