Dead RF31 DSSI Disk..

[Charles Dickman]

KZQSA is Qbus SCSI board with SII chip. It was used for CDROMs and such. No
DSSI here.

KFQSA is Qbus DSSI.

KA670 has built in DSSI controller, so the RF drives should be connected to
it.

DSSI drives are intelligent and can be accessed from VAX firmware utility.
I have done this with KFQSA, KA650, and RF71. Drive has internal operating
system with a command prompt, diagnostics, etc.
