That might be the same thing as the Dataflyer SCSI.
I think it was a basic ribbon that attached to the IDE interface
giving you the use of SCSI devices minus the performance.
You can also attach IDE drives to a SCSI chain if you wish with a
suitable IDE-SCSI adaptor. Not sure what circumstances this would be
useful.
If you have an ethernet card you could always network to a cheap
machine with SCSI drives acting as a server. But you'd just get about
500k/s as opposed to 3-6mb/s on a Blizzard SCSI style setup.
There is a package on Aminet that allows you to network using the SCSI
interface, not quite sure how that would work but I seem to remember
there being a big snag to it's usability.
