Just aquired a couple of Q950's. One has a tape drive and the other an Apple

Is the tape a viable option for backup?

Yes, it is a DDS-1 drive, and is supported by Retrospect.

The PDS card provides two "intelligent" SCSI buses for use by A/UX.

The internal one is 10 MB/sec; the external one is 5 MB/sec.

There is a cache RAM on the card. There is a CPU on the card.

The entire purpose of the card is to allow the 68040 on the Q950/WGS 95 to 
continue processing A/UX while the CPU on the card completely handles the 
disk accesses.

The card is only useful when running A/UX, however.

Under MacOS, the machine will have two usable SCSI buses. Under A/UX, the 
machine will have four usable SCSI buses (but only the ones on the PDS card 
are recommended for use).
