External SCSI Optical Drive

Well a 25-pin D-sub connector on the parallel side and a Centronics SCSI connector on the other end, but this makes a bulky door stop; a nice red brick is more compact.

There is no way a parallel port can drive a SCSI device, and if by magic it did, it would be slower than molasses in winter.  There were slow Zip drives and the like that were made to work with the parallel port for laptops, but that was not a SCSI connection.

Ok,

I'm guessing that you saw a 25-pin SCSI-1 or 2 port and mistook that for a parallel port, this was a big problem with owners of the A3000.  You did not say what platform you are wanting to hook up your drive to, and this could be an issue.  Lets say it is an Amiga with an A2091 SCSI card, then you want a 25-pin D-Sub to 50-pin Centronics SCSI cable like this one:http://www.ebay.com/itm/SCSI-I-DB25M-Centronics-50M-3-ft-Molded-Cable-NEW-/370980441739

There are other types, but since you didn't specify, this is the most common.

Is that how a parallel Zip handles it, with an IDE conversion in the drive?
