Thanks for that information about the connection symbols, although it
would have not helped here, as the IBM SCSI card has no such symbol.

Why the hell SE and HVD use the same connector is beyond me. Given
there is a risk of damage connecting the two together, you would think
the SCSI standard would specify another connector.

My UMAX scanner has a 25-pin D-plug as the SCSI connector, which seems
a bit stupid - and is not reliably seen on the Sun. I have it on its
own bus.

I know someone at work managed to blow up his laptop's motherboard by
fitting a SCSI zip drive which also uses 25-pin D-plug.

It all seems so stupid to me. Next someone will decide to use 9-pin
D-types as mains connectors!
