Adding a bit of nitpicking to Dan's excellent SCSI advice.   Both
SCSI busses on the 7300 are compliant with the SCSI-2 specification.

The internal bus supports the Fast SCSI-2 spec (10 MB/s).

The external/internal bus supports unenhanced SCSI-2 which is just 5 MB/s.

hum. Do you have some doc reference for this?

While I may sometimes be
mentally unstable, my 7300s with long chains are rock solid.  And my
tech docs say the interface is *SCSI-1*.

Well, it is apparently good to challenge one's memories every so often. I checked where I thought I had read that--Developer Notes--and cannot find it explicitly stated anywhere that the slow bus is SCSI-2 compliant. So now I'm curious as to where you found it written that it is not?


The closest I can get is that the slow bus is reported as an NCR53C96 chip (cell embedded in CURIO) and the 53C96 chip is described in its datasheet as supporting some SCSI-2 features--but again, it doesn't come out and say that it is a SCSI-2 chip.

It's not looking good for the accuracy of my memory. Apologies to the list (and thanks to Dan) if I misremembered.
