SCSI controller chip - NCR 5386

The SCSI controller chip used is the NCR 5386. Documentation can be found on Bitsavers[1]. --Torfinn (talk) 08:29, 31 May 2017 (UTC)

The NCR 5385 family consists of the following members:

NCR 5385
first family member, max transfer speed 2.5 Mbps (theoretical)
NCR 5385E
"stop gap" measure to NCR 5386 customers
NCR 5386
superset of NCR 5385 / 85E, production from March 1985
NCR 5386S
NCR 5386 + synchronous operation to 3 Mbytes / sec
