In an attempt to attach a SCSI tape drive to my mac, I searched for a cable that would connect the DB25 on my MacII to a standard SCSI 50 pin. I ended up buying what is described as a SCSI System Cable, which is a DB25 Male to Male 50 pin Centronics cable. Does the Centronics fit _anything_ in the SCSI world or should I just get my money back? Graham Murphy -- High Altitude Observatory National Center for Atmospheric Research P.O.

I've seen it used for Apple standalone disk boxes, although DB25 is also used there sometimes. HP has Winchesters from 100-660 megs, as well as MO drives and a DAT tape drive that use it for the external cabling. At least two companies sell Exabytes in boxes that use the connectors. There are insulation-displacement connectors available that go from those connectors to ribbon cable. AMP calls this general type of connector "CHAMP" and Amphenol calls them "Micro-Ribbon".

This connector is also referred to as the Amp "Champ" or "low-density shielded connector".
