It looks like it is sleeping...
It sort of is, because the Science Museum have only put 3 of the 4 big bays of electronics on display. So they have made a T shape instead of a Cross. They have done this to put a Russion computer of the same era in front of it. A really poor decision I think.
The display also misleads visitors into thinking that these 'supercomputers' were only used for strategic planning in the cold war, wheras to the best of my knowledge most of the CDC 6600s were in fact in Univerities of the 'west' and mostly used for research and weather prediction.

The blank console in the picture reminds me of an incident of mine around 1971-74 ish. The 6600 was the main computer of the University of London and the (physically large) hard disks contained programs and data files for many hundreds of students. I worked for the University Conputer Centre and got to use the machine to myself after the day's work was done. So one evening I was working away at some modifications to the operating system.
In the photo you can't see it but underneath the keyboard, they was a big power switch to turn the console on/off. While reading some notes, I leaned back in the operators chair and accidentally kicked the console switch off, without realising it.
When I looked up the screens were blank, so I thought I had crashed the system. When nothing at the console revived it I reluctantly restarted the entire computer, when that also did nothing I thought the disks were corrupted so I reluctantly did a clean-start which wipes the disks.
When that too did nothing I finally realised that the initial problem was merely that I had switched the console off... So I switched that back on, but now I had removed all the student's files !
Aaargh... We did have provision for that of course, but it took me all night, alone in the huge computer room, to reload all the backup tapes so that the students could have normal service at around 9 am in the morning.
