I think that F/W SCSI-II (FAST-10) predated Ultra (FAST-20) by a few years, anyway: F/W
SCSI was available on the
SGI Onyx (in either diff or SE) which was introduced in 1993.
I'm a big fan of SCA drives + adaptors for old systems since the 50-pin drives are
noticeably ancient now (most
at around 1998 or before). A SCA drive + 50-pin adaptor is much newer (and 50-pin drives
of any capacity (9GB+)
have a substantial premium over SCA and 68-pin models. Some machines (Sun lunchboxes in
particular) don't have
space for a SCA drive + adaptor board, though.
The latest SCSI standard (SCSI-IV I think) no longer requires drives to support 8-bit
transfers and asynchronous
mode. Some of the drives I've seen still do, but be warned...
