  SCSI stands for "Small Computer System Interface".  It is an
enhancement of SASI (Shugart Associates Systems Interface).
I don't believe that SCSI has been accepted as a standard by
ANSI yet.  The organizations behind SCSI are Shugart and NCR.
Does anybody know of others?

  SASI was first done as a cpu to small disk interface -- suitable
for a single user, small system.  SCSI expanded SASI to include
support for many different types of devices.  These devices must
be somewhat "smarter"; the cpu won't guide its every operation.  A
SCSI command is given to the device and the device does it, relinguishing
control of the bus if the operation takes a long time.

  There have been a number of articles on SCSI recently. Check 'em out.
