The TU10 is a classic big tape drive from Digital Equipment Corporation, able to store 5-20 Mytes on a 2400' 0.5" wide tape on a standard 10-1/2" reel. It supports 7-track operation at 200, 556, and 800 BPI, and 9-track at 800 BPI.
The tape transport utilizes a single capstan, with vacuum columns. The drive contains a fair amount of electronics, in the form of FLIP CHIP modules in a 19" wide wirewrap backplane (mounted fore and aft in the drive itself).
It was first used with the PDP-10; to connect to UNIBUS PDP-11's, a TM11 magtape controller is used. The TM11 controller connects to a 'Master' drive, which includes extra modules in the backplane; additional 'Slave' drives (up to seven) may be connected to the Master drive. Details of the controller-Master interface are given here.
