Re: How to use a WD1002S-SHD MFM - to - SCSI (SASI?) adapter card

Hi John,

In the past I've written drivers for both this chip (5380) and SCSI
drives using this WD MFM interface board. It uses an old version of SCSI
that is unlikely to be compatible with todays drivers.

What you may be able to use are the very low-level SCSI "service"
ulitities that came with some controller cards in the 80's. Adaptec used
to supply a few low level utilities with there ISA controller cards so
maybe they have something?

Regards,

Paul.
