ZIP drive on SCSI segment w/ other devices -- problem or not?

[James W. Durkin]

I've been warned off of placing a SCSI Insider ZIP drive on the same
segment (the 50-pin narrow connector of an Adaptec 2940U2W PCI card)
as other devices such as CD-ROMs.  The expected problems have been
variously described as "will damage the other devices on the segment",
or "will cause the controller to reset indefinitely".  Nothing
particularly specific, and nothing I've been able to confirm from
looking through the various unofficial Iomega sites on the web.

Instead, it's been suggested, that it should be driven from the
supplied (Adaptec sourced, I guess) controller.  Seems a waste of an
ISA slot, plus cabling hassles, etc.  But if there is a legit reason
for it, I guess it's tolerable.

So, truth or fiction here?

FWIW, I'm no fan of ZIP drives.  They're sort of a sneaker-net
standard here, so I live with them.  I would prefer to live with them
in the most efficient manner possible though.

If it matters, it's a PII system with all other storage devices (save
floppy) hung off the 2940U2W, running RH 5.2.
