Same here. But it's not outside the range of possibility that *someone*
called them X and Y, although I don't know who did. Doug Jones doesn't
Let's not forget the System/3 96-column cards. BA8421 (sort of like
7-track mag tape), with a really wacky way to combine the columns to
make 8-bit bytes.
Univac, of course, had their own system with their double-45 column
system, round holes and all.
