The fun thing I discovered was that although the glyphs were different,
the key at any given location on the keyboard punched the same combination
of holes regardless of whether it had a BCD or an EBCDIC code plate.
Thus, if you could touch-type the BCD keyboard, you could sit down at
an EBCDIC machine and create your card deck (and vice versa with a few
gotchas, see below).  The special characters printed on the cards would
be wrong, but the computer would see exactly what you wanted.  That came
in handy at university, where there would often be a line-up for one
flavour of keypunch while the other ones stood empty.

The one catch was the the 026 couldn't punch everything that a 029
could; you'd have to resort to the multi-punch key for the less-used
characters.
