    I know it's a SCSI cable, but what is it used for? It looks like an internal ribbon cable, but it's got (what I think are) external SCSI connectors with an internal SCSI connector in the middle.

    What's it for?

    You're right. Those are external SCSI adapters on the ends and an internal in the middle. Where did it come from?

    I could imagine the internal plug attached to a SCSI card/onboard SCSI with the two external connectors going to the back of the computer's case.

    Those Centronics-style connectors were only used for SCSI-1 IIRC. In other words, this cable is a relic. What's interesting is that the two external connectors are on opposite ends of the cable. Most SCSI cables have multiple connectors at one end of the cable.

    we just threw away a batch of these from the cable graveyard :p
    Thats the old DB50 or DB25 I think.
    The last bit of SCSI we have is on the Avid workstation.
    Its the Ultra one.
    I say good riddance!!!

    I found it in an old box of scsi connectors while looking for a terminator.

    Gotta love working in universities... Always some good old stuff tucked away in storage.

    I'm pretty sure it's for an external SCSI drive. The drive goes in a case, and the case has mounting holes for two external SCSI connectors.

    The drive connects to the middle connector. External cables connect to the two end connectors.

    That's it exactly. I have several more if anyone needs them.

    Yes, that's it. I took one out of a case once to use as a joiner for two other external SCSI cables that were 50Pin Centronics to 50pin HighDensity. At the time I didn't have a HighDensity50 to HighDensity50 connector.

    It's possible that's why this cable was removed.

    Also, some Firewire bridge boards were designed to fit the hole(s) left by the 50 Pin Centronics connectors.

    looking for trash files
    hooking the SCSI disks to stuff. and then hooking that stuff to other stuff.

    thank (insert deity here, or lack thereof) for sata and no more jumpers!
