Not sure that I entered any actual machine code that way, but I think
I did enter some binary data in this fashion, yes.  I can no longer
remember why.  But I think I screwed it up by having a card in my deck
that was punched 7+8 in the first or second column, which was used in
the card reader to signify end-of-job.  Oops.

Well, there was no ascii.  Each column had room for 12 holes being
from top to bottom +, -, and the digits 9-0 (in the /unlikely/ event
that I remember this correctly).  To punch several holes in one
column, you could just put a thumb on the card so it wouldn't advance,
and punch away.
