SCSI (X3.131-1986), now usually called SCSI-1. This standard has now been withdrawn. Up to 8 devices on a cable, passive termination, 8bits/ch 5MB/sec

The SCSI standard was designed for disks, but is very flexible and was used for other devices, notably scanners and slower devices such as Zip.
FCconnection used a 50 connector cable, originally with Centronics connector, but later with a 50-pin D-shell connector, similal to a DB-25 RS-232 serial connector.
