II FX SCSI PROBLEMS WITH DEVICE THAT WORKS WITH II SI

The strange stories continue.  I have a Xerox Scanner 7650 that used to
work fine with a IIfx and a IIsi, but Xerox had shipped it with a frayed and
tattered cable (How did they win the Baldridge Award, by buying it?)

So the cable stopped working, and I got a new one from MacConnection. 
Interestingly, the cable and scanner work fine with the IIsi's SCSI port
BUT the IIfx even fails to see the scanner connected.  Trying to force it to
mount or update said the SCSI chain was not terminated (even though this
works fine with the IIsi).

Could it be that good old Apple Computer has different (incompatible)
types of SCSI ports on the II fx and si.  (eg the modem ports on them are
built differently a few weeks ago each of my WorldBlazer modems failed
to work with the II sis while they worked with the II fxs.  [Maybe Apple
should also be getting a Baldridge Award ;-)  ]

Are you using the black terminator that comes with the fx?  The fx has 
a SCSI bus that requires different termination than any other pre-Quadra
mac.
