Well, I suspect the 1K-sector drive I have is ontopic, actually. :-)

But the Tandy drive you suggest wouldn't do because it's not SCSI, and,
though I omitted the adjective in the text talking about that drive
(expecting it to be inferred from context), what I really meant is
"...an example of a SCSI disk drive with >512-byte sectors".
