Don't you know that when you say something like that, somebody like me is going to come out of the woodwork? I removed the internal SCSI harness from an external Exabyte 8500C a while back and replaced it with what's commonly called "SCSI-2" connectors and harness. What I removed was exactly the 3-row DB-50 connector you describe. And don't you *know* it came off a Sun 4/470? I recycled the DB-50 connectors by putting them to use connecting (8) 8" IPI drives to an SGI Crimson. 19.5G and lots of heat! Digging thru our SCSI cable box the other day I found external cables with that DB-50 on one end and "SCSI-2" on the other. And found another with a modern 68-pin SCSI connector on the other end. Naturally I couldn't find the cable I was looking for. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
