mostly remember the shop-vacuum-like whine of the vacuum pump, and the fluttery thwack of
the tape loops forming on load-up. The other tape motion sounds didn't stick in my
memory so much. I do remember the buzzy grind of the capstan motors on the C240's tape
drive; I don't recall whether that drive's OEM was Fujitsu or Hitachi, but I found
it quite enjoying to watch as an engineering student. Hmmm, on our TU77, the vacuum
pump was not that audible, but
then it was in a room with a LOT of noise. Liebert air
conditioner, 11/780, RM05, RP07 and then the TU77. When the
drive was not running flat out, the bup-bup from the tape
columns was not real loud, but when you were pushing data
fast, like BACKUP with /buffers=5, it made a pretty steady
BRRRRRR noise.
