 A TU56 drive | |
| Manufacturer: | Digital Equipment Corporation |
|---|---|
| Drive Controller(s): | TD8E, 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.
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 | |
