Apple WS 9650 manual Fast Scsi

Basics Fast SCSI - 26

Fast SCSI

The Power Macintosh 8600, 9600, and WS 9650 offer Fast SCSI support on the internal 50-pin SCSI-2 connector, which provides for significantly enhanced data throughput. The internal SCSI bus on these computers supports transfer rates up to 10 MB/sec.

Only one internal terminator is allowed on the Fast SCSI bus. In the PM 8600 and 9600, the rear hard drive (the last device in the chain on the Fast SCSI-2 bus) is terminated. None of the other devices on this bus should be terminated.

In the WS 9650, however, the unit ships with only unterminated devices attached to the Fast SCSI bus (that is, the CD-ROM drive and the optional tape drive). Therefore, there is a 50-pin terminator attached to the end of the SCSI cable.
