The scheduling program had a few requirements that would have
been difficult to meet with an appointment book made from dead
trees:

  1) The scheduling program was accessed by multiple (Hazeltine)
     terminals in different rooms, often simultaneously.

  2) The schedule needed to be updated on the fly during a shift.

  3) The cable had nearly a dozen operating channels fed from
     over a dozen VCRs and a few open-reel (1/2" and 1") video
     tape machines.  The algorithm to determine where/when a
     playback could be scheduled was too complex to be done by
     gray matter without an unacceptably high error rate.

Now, if the Raspberry Pi had been available at that time
(1979-1980), a whole lot more cool stuff could have been done.
(Had to do something to keep the discussion on topic.  :-)
