Gary,
So your drive is a 68-pin drive and you've got it hooked to a 50-pin
cable? That is what I need. Where could I find such a beast? Are they
sold new by any place that you know of? Or is it something I'm likely to
find on Ebay?

I have some RZ29's that are 68-pin and I'm wondering if there is in
adapter? I suspect not, but just asking.
If I'm not mistaken, it is possible to "go the other way" and use
50-pin devices on a 68-pin cable with an adapter that terminates that
"extra" lines, correct?

Yep, I have a 68 pin to 50 pin adapter on a drive on my Amiga. 68 pin
is SCSI-3 and is 16 bits per transfer cycle rather than 8. There are 50
to 68 pin adapters, but the termination for half the buss is a rare
animal. I'd just have everything unterminated, and have a good active
term on the end of the 68 pin cable. The down side is everything is
slowed to SCSI-2 standards. I want to find a SCSI-3 CDrom to avoid that
if possible, as I just bought a SCSI-3 hd for my Linux box here. I want
to integrate a small SCSI-2 drive as my /swap partition.
