Actually, the Zip drive uses a 68-25 converter, and interestingly the
cable between the Zip and the CD burner is a 25-to-50, so no converter
necessary on that one. I will need to connect the 68-way terminator to
a 50-68 converter, though.

OK, so let me make sure I have this right....
Should I readjust the SCSI cable on the Cyberstorm so that it's
attached in a "V"-shape -- i.e. have it branch out into TWO cables --
one with one port, in which there's a 68-pin terminator, and another
with the remainder of the ports?
