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!
I want to know what all the blinking lights mean..! It would drive me mad if anything I had to use flashed and blinked at me like these things..!
The blinking lights were mainly used to show the state of the internal data registers to make sure they were all working. A dark register light usually means that circuit has lost power and needs to be serviced.
