Are people in the habit of burying them? Funilly enough, some people did indeed think connecting a SCSI device to an Amiga parallel port was a good plan.

Fascinating link Iggy. Author clearly didn't know how you can attach 16 bit and 8 bit devices to the same cable and controller (3 terminators in the chain, but number 3 just masks off the extra 8 bits of data on the 50 pin ribbon cable from the 8 bit devices beyond it. Not a hack.

But hey, never can happen on an Amiga, right? You are saying there are no 16 bit SCSI controllers on the Amiga. Potentially, more than you might think. Try plugging in an FAS216U to an Amiga controller with a standard FAS216 based controller...

You might also get some joy with the expansions based on the NCRC94, such as the Flyer. 16 bit internally, but AFAIK Amiga implementations do not use 16 bit 50 pin SCSI cables, except as 8 bit 50 pin SCSI cables.

I would strongly urge SCSI card owners to look up their card, controller chip, and upgrade potential and make their own minds up, rather than relying on flame warriors who have used less than a dozen different Amiga SCSI controllers, and who simply "believe" that Amiga SCSI can only ever be 8 bit except with a Phase 5 product or a Warp Engine. Even a humble WD33C3 controller can sometimes do up to 10MB second synchronous transfer, but sadly most A1200 Blizzard SCSI kits are limited to SCSI one speeds. Tough.

Jope, good luck, the drive side should be OK at least.
