Well, since the Syquest is a SCSI device, and since the ICD host adaptor 
supports the Syquest, you would be even cheaper off by purchasing a bare SQ-555
mechanism and hooking it to the ICD.  Then it could be used in both Mac and 
ST modes.  Given that you can get the mech cheaper than a finished Mac product
(which I would assume is true), this would be the more cost effective way 
to go.  Alternately, you could buy the Mac unit, open it up, take off the 
25pin SCSI cable, put on a 50pin, stick an ICD in there, and away you go.  I 
am unsure if an adaptor exists, but the cables are so cheap that replacement 
would probably be easier (and you would then not have the adaptor connection
to worry about).  This is assuming that there is no Mac specific circuitry 
or boards in a finished Mac drive of this type (I don't think there are, just
a weird 25pin cable).  Of course, the SQ-555 mech uses a standard 50pin SCSI.
