I am wondering if anyone has a list of modifications to the SCSI interface
described in the September 1985 Dr. Dobb's Journal that would make it
compatible with the Mac+ addressing scheme.  The interface was distributed
by Fastime, whose telephone is "out of service or disconnected."  Perhaps
John Bass can enlighten us.  Are you there, John?

My hope is to use the driver in the 128K ROM (and any bug fixes applied to it
in the future) rather than a somewhat untested driver made necessary by the
non-standard addressing of the SCSI interface.

By the way, Apple picked a "standard SCSI connector" which is unlike the
DIN 50-pin "standard SCSI connector."  Apple's is like a Centronics printer
connector, only with 50 pins rather than 36.  Many Mac+ SCSI drive vendors
seem to have gone straight to the 25-pin D-subminiature connector on the Mac+,
but the Iomega SCSI Bernoulli Box uses the Apple 50-pin arrangement, also
requiring an Apple terminator plug (same connector.)
