Small Computer System Interface (also known as SCSI, skuz-ee) is a parallel interface standard pioneered by Larry Boucher of Shugart Associates and later Adaptec.[1]

SCSI in the PippinEdit

The SCSI interface was first adopted by Apple Computer with the Macintosh Plus and was in use across the Power Macintosh line at the time the Pippin platform was in development. An internal SCSI interface on the Pippin console motherboard is normally used to connect solely to the built-in 4x-speed CD-ROM drive, set to SCSI ID #3.[1]

In some consoles offered by Katz Media, the SCSI interface is daisy-chained through the CD-ROM drive to an external SCSI port on the back of the unit. A developer ROM or ROM revision 1.2 or later is required to support other SCSI devices besides the internal CD-ROM drive. Some developer consoles have been modified with passthrough ribbon cables to support additional SCSI devices.[2]

A SCSI expansion dock was reportedly tested for consoles that lacked an external SCSI port, but would have required a ROM update to rev. 1.2 or later.[3]
