They will probably kill the SCSI market by confusing people. I personally would get miffed if I got a wide/fast interface and the *wrong* kind of SCSI disk. I may be remembering this wrong (no reference material handy), but I believe that SCSI/2 allows both the target and the initiator to negotiate the width of the transfer down from 32 bits. Therefore, you can still use a 32-bit SCSI/2 device with an 8-bit SCSI controller, and an 8-bit SCSI device with a 32-bit SCSI/2 controller. -- Bruce Robertson Hundred Acre Software, Reno, NV Domain: bruce@pooh.com UUCP: ...!uunet!tahoe.unr.edu!heather!bruce
