Yes indeed, as others have said, should be no problem to connect. When these things were new, I went with the Syquest alternatives, EZ135, EZFlyer and SyJet. For Falcon no issues other than driver, for ST you will need the addition of an ACSI to SCSI link such as Link, Link II, Toplink etc.... The same will be true for the ZIP equivalents, ZIP 100, ZIP 250 and ZIP Jaz drives.
SCSI cables are not an issue, but for the ST the ACSI to SCSI usually use 50 way centronics, so you will have to make sure that the other end matches to whatever the drives connection is. Some will be 50 way centronics DB50, some will be 25 way centronics DB25, slightly later models will be 50 pin half pitch (SCSI 2). They tend to get termed slightly differently, but generally look out for centronic DB50, DB25 or SCSI2. There are 'loads' of different interfacing SCSI cables, you just need to make sure the ends convert from the ST (50 way centronics usually via whatever ACSI to SCSI link) or Falcon (SCSI 2) to your SCSI device, simple as that.
