I think Chuck has it backwards, AT Attachment as defined by the ANSI

it did not surface publically until well after the ANSI committee adopted AT
Attachment, abbreviated ATA.
Do you, by any chance have the dates?
A casual look seems to show the WD IDE ("Integrated Drive Electronics")
being used by Compaq in 1986?, although not necessarily NAMED "IDE", yet.
A casual look seems to show ANSI ATA as being early 1990s.
The AT in AT Attachment or ATA has never stood
for "Advanced Technology" although many presume so.
DOES it stand for something else?
It is generally assumed that it refers to the IBM PC/AT (aka 5170), where
AT DID, indeed, stand for "Advanced Technology"
