Well, I think what we call "XT" drives are "IDE" (I was told there were XT-Bus and AT-Bus interface drives - A590 uses XT-Bus drives internally.) What do I know, I'm a software guy. :-) >It'd be good to know because IDE drives should eventually be considerably >cheaper than comparable ST506, SCSI or ESDI drives (mainly because they're >PC-specific and therefore will see disgusting economies of scale...) Probably. They're already cheaper than SCSI drives by a fair amount (less electronics/chips/software/etc for the menufacturer). However, SCSI drives are coming down quite a bit. BTW: for the person who liked HDToolBox so much: Thanks. It could be better (and will be next rev), but it's a light-year better than the 2090 prep program (IMNSHO - In My Not So Humble Opinion). :-) -- Randell Jesup, Keeper of AmigaDos, Commodore Engineering. {uunet|rutgers}!cbmvax!jesup, jesup@cbmvax.cbm.commodore.com BIX: rjesup Common phrase heard at Amiga Devcon '89: "It's in there!"
