Tape drives from the B205 make up part of the computer system that controls the Time Tunnel.
Year of feature (shown above)
As I have oft-timed repeated it was a startling revelation for me to eventually learn that all of THE TIME TUNNEL (ABC 1966-67) tv series' peripheral computer hardware exhibited in the Project Tic-Toc main control room standing set was actually surplus (some secured from the U.S. Air Force).
I originally thought it was all built in the 20th Century-Fox Television Studios prop department.
Mix & Match... It looks like, in the middle photo, they have 3 Q7s hooked-up to several high speed Burroughs tape drives. That would never work. Plus, they could've ripped a hole in the Space-Time Continuum!
