TU79
From Computer History Wiki
TU79 was the name used for two entirely different magnetic tape drives from DEC: one from the late 1960's, and one from the late 1980's.

Early TU79
Very little is known of this one: it operated at "75 in/s [tape motion rate] with a maximum transfer rate of 60 kc". It could be configured with either 7-track or 9-track head. It could be used on either that PDP-9 (with the TC59 Tape Control Unit), or the PDP-10 (with the TM10 Magnetic Tape Control).
Later TU79
The later TU79 seems to be a TU78 with minor cosmetic changes; it is configured to have a MASSBUS interface.
