I noticed the other day that the SCSI kit for the Blizzard 12xx enables one to have a SCSI hard disk that can do DMA.  Why wasn't anything done to allow IDE DMA, does anyone know?


Despite it was not available at the time, it would have needed additional logic for bus arbitration (something like the Buster chip) and that would not have been as cheap as the implementation in the A1200 Gayle (?) chip.

Anyway, I suppose you know that there are rather cheap adapters for SCSI to IDE, so you can use cheap IDE harddisks on the scsi bus?
