A standard for connecting
hard disk drives to personal computers. Prevalent in the early 1980s but has since become the
Small Computer System Interface standard (
SCSI).
SASI supported signalling speeds of 1.5 Mbytes / second, which although slow by today's standards, was quite decent
at the time.
Shugart Associates, lead by
Alan Shugart, was the developer of SASI. (Shugart Associates later became
Seagate).
Wanting to get SASI made into an
ANSI standard, Shugart Associates teamed up with
NCR Corporation in
1981 to convince
ANSI to set up a committee to standardise the
interface.
In
1982, the technical committee, as well as making changes to the interface to improve performance of SASI, changed the name to Small Computer System Interface, or
SCSI.
In
1986, the first true SCSI standard was published.
