An enhanced, dual-drive version of the [[TU55]].
The '''TU56 DECtape Transport''' is an enhanced successor to the [[TU55 DECtape Transport|TU55]]  [[DECtape]] [[magnetic tape drive]]. The usual configuration was dual-drive (referred to as 'dual transport'), but a single-drive version, the '''TU56H''', was available. The '''TU56M''' (dual) and '''TU56HM''' (single) model included 5 G888 Read/Write Amplifier [[FLIP CHIP]]s, for use with [[device controller]]s which do not include that functionality.

The TU56 contains a small [[backplane]] holding a number of [[FLIP CHIP]] modules. The module location chart for the TU56 backplane is (starting at the right-hand side, viewed from the board-insertion side):

TU56

A TU56 drive
Manufacturer: Digital Equipment Corporation
Drive Controller(s): TC08, TD8-E, TC11
Media: DECTape


The TU56 DECtape Transport is an enhanced successor to the TU55 DECtape magnetic tape drive. The usual configuration was dual-drive (referred to as 'dual transport'), but a single-drive version, the TU56H, was available. The TU56M (dual) and TU56HM (single) model included 5 G888 Read/Write Amplifier FLIP CHIPs, for use with device controllers which do not include that functionality.

Card locations and counts

The TU56 contains a small backplane holding a number of FLIP CHIP modules. The module location chart for the TU56 backplane is (starting at the right-hand side, viewed from the board-insertion side):

Slot A B Use
1 G848 Left forward
2 G848 Left reverse
3 G859 G847
4 M941 M922%
5 M531 M113
6 M908 M113
7 M908 M117
8 M040 M302
9 G851%
10 W032#
11 W032#

15 M040 G888*
16 M117 M113
17   M922%
18 M941 G847
19 G848 Right forward
20 G848 Right reverse
