It can't, by modern standards!  ASCII 1967 has 93 printable
characters, including both upper and lowercase letters and 32
punctuation and symbol characters, but ASCII 1963 has only 63 -- which
fits into the Model 28 type box of 64 pallets.

I've attached a (mirrored for easy reading) scan of a Model 35 type
box to this message, and I was prompted to write up a little bit about
ASCII and the Model 33/35 line here:
