TU10 drive
Tape speed: 45 ips (Forward/Reverse)
150 ips (Rewind)
Size: 19"W x 26"D x 26"H
Weight: 150 lbs


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.

Module Locations

This is the module location chart for Flip Chip modules in the integral backplane in Master drives:

Slave drives appear to hold a sub-set of this list; slots 6-15 are empty in Slave drives.

Note: In the TU10 Slave backplane drawings, slots 28-30 show different module numbers; however, those original module numbers are crossed out, and the same module numbers as in the Master drive are written in by hand. The captions in those slots (e.g. "Peak Detector"), however, match those of the written-in boards, not the boards originally listed. Thus, the original numbers may be erroneous.
