Many decks have cards in various binary formats which utilize all 12 rows of
each column. I store these in the simh binary card format, which is also the
format that Brian Knittel established with his Documation card archiving
software. That records each card column as a 16 bit word with the bits from most
significant recording rows 12, 11, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 followed by
least significant bit padding of four 0 bits. As these are written as integers
in the native microprocessor running the code, the endian issues may arise.
