Cable length, impedance, and reflectivity have been problems with
the Apple SCSI bus since the bus first appeared!

Granted, certain Macintoshes/Systems have had better/worse performance
in this area, but I have *never* had a Macintosh that did not have
a SCSI cable problem with one or more of my devices. It usually depends a
lot on the SCSI device being hooked up.

The moral of the story is to buy your SCSI cables *carefully*.
Third party cables that are thin and long are obvious recipes for
problems. Get short thick cables, preferrably from Apple. I know that
Monster Cable (the guys who did the *thick* audio wiring) now makes
a SCSI cable. That is probably a good bet.

BTW: I run an fx with the CD ROM being the third device on the chain
     and have *no* problems. Just good cables.
