Computer History Museum had one when I stopped by about 10 years ago. Not certain if operational as anything other than a cozy bench. Anyone know?

  They used Freon coolant so it's possible they can't/won't

    Couldn't they use one of the freon substitutes like R-407c?

      Not my area of expertise but if I had a literally priceless old supercomputer, I wouldn't necessarily want to risk running it outside of its intended operating conditions (especially after 40 years)

  No, the Cray is not operational. Only a few things at the CHM are operational: the PDP-1, the IBM 1401 lab, and the RAMAC disk drive.

    When I was in high school we had a PDP System 10 and PDP 11 where I took a programming course on PDP-11 assembly language. It makes me feel old knowing these weren't antiquated at the time.

      Wow! Did you ever meet Charles Babbage? ;)

        No but something nearly as bad was typing on punch cards and having to feed them into a card reader to get the code into the computer. And all but one of the terminals was a TTY at 110baud and printed on paper. There was a single Dec VT100/102 terminal you had to get in early to use.
