Funny you should raise this:

"As part of Sun's continuing efforts to enhance SunOS, SPARCstation 1
incorporates a new SCSI driver. This driver supports a more consistent set
of SCSI operations, thereby simplifying the addition of new SCSI devices
to the system. Equally important is the support for synchronous SCSI for
high-speed data transfers." -- from an article on the design of the 4/110
(SPARCstation 1, a name that puts me in mind of a spark-station), by
Bechtolsheim et al in Sun Technology, Spring 1989, page 53.

They talk about revised documentation too, but don't specifically mention
documenting the SCSI driver.
