The Apple rev. C SCSI card, that is.  Luckily, the Apple DMA "High Speed"
SCSI card does not have this problem.  It is also not proprietary like
the RAMfast card.

Any driver written to interface with an SCSI Ethernet box would be limited
to supporting the Apple HS card.  The question then becomes, do the people
who are interested in such a driver have mainly this card?
