  • HP50 (Half Pitch 50) Male to Centronics 50 Male
    • HP50 Male
      Half Pitch 50 Male (Micro DB50 Male) - Used for scsi-2 applications: scanner, removable storage drive, controller, external cdr/cdrw. The Micro DB50 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. Most 8-bit SCSI FAST (up to 10 Mbytes/sec) computers and host adapters use this 50-pin High-Density connector. Commonly used on Apples and Mac, and some older Sun 8-bit workstations. This connector is seen increased use on Scanners and Iomega Zip Drives.
    • 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.
  • SCSI 2 to SCSI 1
    • SCSI 2 - This standard was introduced in 1989 and gave rise to the Fast SCSI and Wide SCSI variants. Fast SCSI doubled the maximum transfer rate to 10 MB/s and Wide SCSI doubled the bus width to 16 bits on top of that (to reach 20 MB/s). However, these improvements came at the minor cost of a reduced maximum cable length to 3 meters. SCSI-2 also specified a 32-bit version of Wide SCSI, which used 2 16-bit cables per bus; this was largely ignored by SCSI device makers because it was expensive and unnecessary, and was officially retired in 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.
