  • Centronics 50 Male to HP68 (Half Pitch 68) Male
    • Centronics 50 Male - At one time this was one of the most common SCSI connectors. Used for scsi-1 applications: older scanners, controllers, external scsi device cases. The Centronics 50 connector has 50-pins arranged in two rows one on top of the other. The top row has 25 pins and the lower row has 25 pins. Used mostly with older 5 MB SCSI-1 Systems. Often called Low-Density SCSI-1 connector. Most SCSI SLOW (5 Mbyte/sec) computers and host adapters use the Centronics type 50-pin connector. Also some 8-bit Fast computers and host adapters.
    • HP68 Male - Probably the most common SCSI connector used today. Used on all SCSI Wide applications and some old DEC single-ended SCSI this connector provides a highly secure connection. Used for scsi-3 applications: scanner, removable storage drive, controller, external cdr/cdrw, ultra/2. The HP68 connector has 68-pins arranged in two rows one on top of the other. The top row has 34 pins and the lower row has 34 pins.
  • SCSI 1 to SCSI 3
    • SCSI 1 - The original standard that was derived from SASI and formally adopted in 1986 by ANSI. SCSI-1 features an 8-bit bus (with parity), running asynchronously at 3.5 MB/s or 5 MB/s in synchronous mode, and a maximum bus cable length of 6 meters (just under 20 feet -- compare that to the 18 inch (0.45 meter) limit of the ATA interface). A variation on the original standard included a high-voltage differential (HVD) implementation whose maximum cable length was many times that of the single-ended versions.
    • SCSI 3 - Before Adaptec and later SCSITA codified the terminology, the first parallel SCSI devices that exceeded the SCSI-2 capabilities were simply designated SCSI-3. These devices, also known as Ultra SCSI and fast-20 SCSI, were introduced in 1992. The bus speed doubled again to 20 MB/s for narrow (8 bit) systems and 40 MB/s for wide. The maximum cable length stayed at 3 meters but ultra SCSI developed an undeserved reputation for extreme sensitivity to cable length and condition (faulty cables, connectors or terminators were often to blame for instability problems).
