The one I mentioned is more likely to work as it has an external interface specially for the older 'legacy' devices.
Edit: hey, someone still sells the same card I have, which is an old Adaptec 2904 like
this one.That's okay for me because all my SCSI devices are slow: CDR/RW, ZIP and a few 1gb SCSI drives.
If you are only going to connect slow devices, then get that one, it will definitely work with that ZIP drive and it is cheaper than the ones in the previous links. But if you want to put slow devices externally and fast devices internally then get the one I first mentioned.
