Hi Nostromo ,
You might want to take a look at SCSI Source. OK, the're way overpriced, but they do show decent pics of all the various SCSI connectors.
http://www.scsisource.com/scsi_adapters/I bought an external HD50 male to DB25 Female adapter from them to use my Zip 100 on my 4000T.
If the Zip disk is formatted properly, it should just show up on WB. You'll want to make sure all Zip disks are formatted the same way, i.e. through IoTools on OS 3.9 , to avoid any diskchange issues..
