That makes a lot of sense actually. IBM was always being different.
"Hmm, we *COULD* use the character set developed as a standard; nah,
let's just continue extending card code! Hello, EBCDIC."

Though, come the 5150 (IBM PC), they were doing slashed-0.


DEC I'm pretty sure stuck with slashed-0 the entire time, though the
PDP-1 may or may not have been an exception -- it's oper. console was
an IBM Model B typewriter, so it may or may not have had any slashes
at all.

Cheers,
Christian
