This room appeared only in Black Sun and Space Brain. The room seems to have been upgraded with more computer equipment between episodes, although the plan is much the same. The communications post (which has no code letter) has gone. The alcove on the far wall is now computer panels, and extends behind the other panels. The ends of the two central banks of computers now have more computer panels, instead of blue lighting panels. Finally, the floor is painted red.
Unusually there is a row of computer panels 4 feet in front of the back wall. Normally there would be panels attached to the sides, but instead the row is just 4 inches thick, the thickness of the free-standing panels.

An alternative computer room appeared in The Seance Spectre (see below).
The Space Brain Computer Room is depicted in Moonbase Alpha Technical Operations Manual by Chris Thompson (2021); pages 96-97.
By Bergman's elbow is the Essential Services panel. It is also on the other side of the computer wall (the wall was simply turned around for this shot).
We don't see this side of the room in Black Sun, so this is based on Space Brain (see below). Note the Blood Transfusion Unit panel, normally seen in Medical.
The blue sign by the door states "Top Security Area". While the original set was filmed in early February 1974, this set was filmed on 19th December 1974 on M Stage.
There is a wide corridor set outside the Computer Room. The communications post has the designation "P".
The Seance Spectre Computer Room is identical in design to the standard year 2 tech lab, in turn a variation of the life support centre. This was filmed on L Stage on Saturday 30th October 1976.
