Gee, you are discouraging me, Allison! Out here, ST-351A/Xs have been
common as armpits. Everyone seems to have a couple! Seemed like a
neat/cheap idea. Guess not, though, as you point out below.
Commodore used the 8-bit IDE stuff in their Colts (XT clones) and the
A590/A291 SCSI interfaces for A500 and Zorro-II (no doubt because of Jack
Tameil's infamous penchant for forcing engineers to design in whatever
surplus hardware was lying around the warehouse). I've only ever seen
20Mb Western Digital XT-IDE drives in them.
As an aside, I burn my ROMs from a Colt with one of those drives in it, but
the drive came from an old HardCard.
Is there any specific information out there about W.D.'s implementation
of XT-IDE?
