This is a SCA 80PIN TO 68 50 PIN SCSI ADAPTER. SCA 80 female to SCSI HD 50/68 female pin male adapter. The adapter is designed to support data transfer rates of up to 320 MB.
It is compatible with a wide range of SCSI devices, including hard disk drives, tape drives, and optical drives, but for our purposes, it is for connecting UltraSCSI hosts to our ZuluSCSI, SCSI2SD, or PiSCSI storage devices. The adapter's SCA 80 Pin interface is compliant with the ANSI SCSI-3 standard.
Comes with a 18" 50pin ribbon cable.
