Yep, you're right... I'm used to Centronics because of their printer applications. The SCSI connector on the back of the 9000 Pro is an HD50. The Iomega Zip works very well... just hook it up and the 9000 recognizes it. The default cable and adapter that comes with the SCSI Zip drive is all that is needed. Heck, the 9000 even reads Zips formatted by the Roland G1000/EM2000. Simple.
