Extraneous uses of computers systems.
In the same vein somewhere between 1974-1976 one of our systems guys used to
backup the RP04's on our PDP11/50 to 9-track tape. He would go to sleep on
a mat next to the system. When the backup finished he would then run a
program that would perform a series of head seeks that resulted in a shaking
of the drive and the floor next to the drive. Very expensive alarm clock.
