Qty:

  • DB50 Male to HP50 (Half Pitch 50) Male
    • DB50 Male - Used for early scsi applications such as older Sun Sparcstations. This SCSI connector was also used by DEC, DG and HP. The DB50 connector has 50-pins arranged in three rows one on top of the other. The top row has 17 pins, the middle row has 16 pins and the lower row has 17 pins.
    • 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.
  • DB50 to SCSI 2
    • 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.
