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 
mention it.

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.
