AM-64x DAT High Capacity Tape Drives

PDI-00649-00, A01

10- and 21-slot rack mount VME computers have no external SCSI connector. To install an external
terminator, you  need a special adapter cable, DWB-10200-01. The connector on this cable is compatible
with the external terminator and also allows you to easily attach a portable CD-ROM drive or other SCSI
device.

The figures below show both narrow and wide SCSI terminators:
