Apple //gs SCSI dip switches?? p/n: 820-0153-A

[Raj Wurttemberg <nospam@nospam.com>]

Hello Everyone! After almost 20 years I'm getting back into the Apple
// world. I recently dug up an Apple //gs with a SCSI card in it and
want to hook it up to one of my external SCSI drives.

Unfortunately I don't have the documentation for the card and I would
like to know what the four dip switches are for. The SCSI card is the
Apple Fast SCSI, p/n: 820-0153-A.

I have plugged it into one of my old SCSI drives and tried both an
active terminator and a passive terminator but the Apple SCSI
utilities don't see the attached drives. I know I'm doing something
wrong somewhere... <sigh>

Any assistance would be appreciated.

Thanks,
