Including the other photos, identified so far:

	Cyber 170		(2 machines I presume)
	Siemens 7•890	(1 or 2 ?)
	VAX 780
	a Modcomp mini	(speaking of out-of-the mainstream minis)

Note that that room is just for DD division machines - general computing services: data processing, number crunching, external networking, etc.

At the time, the accelerator control was being done by Norsk-Data minis located in the accelerator control room, as shown and explained to me by someone who had worked on their programming; and there were machines all over the rest of the site associated with things like data-collection from experiment sensors, assorted labs, etc. I recall for instance, seeing a VAX-750 doing sensor data-collection, and a lab filled with some graphics machines, but don't recall what type they were.
