Time sink!
      12/25/15 09:42 PM

Mase, seeing that lady at the tape drive reminds me of an unusual incident
that happened in the early 1960s. I was in a computer room that had about a
dozen 729 tape drives lined up -- this was before disks and was the way we
stored large amounts of data.

All of a sudden, they all stopped and began to unload the tapes from the
vacuum controlled chambers. One of the guys in the room shouted, "Did you
see that?" He then explained a car had just pulled out of the parking lot
in front of the computer room and the reflection of the sun off its
windshield had swept across the line of tape drives.

Back then the tapes had a small piece of aluminum foil near the end of the
tape. It would pass in front of an electric eye and the reflected beam would
signal the drive it was at the end of the tape and shut it down. The
reflected sunlight had swept across all the drives and their electric eyes
"sensed" it was the end of each tape, so each was unloaded.

They had been trying for weeks to find why the tapes would occasionally and
mysteriously unload. Of course they were always looking at the electrical
circuits for the cause.

The next time I was in that computer room, they had curtains on the windows
overlooking the parking lot.
