In 1972, I programmed Burroughs L3000 accounting machines that could read magnetic ledger
cards. I wonder if the Monroe could use the same kind.

You might dump the ROM and look for ascii strings.
I've wondered if it was possible to glue strops of tape wide enough to
cards for these card readers.
Of course, if they were preformatted, it will be a bit more difficult.
I have a few reels of two-inch video tape which I've used to make crude magnetic cards
for old HP desktop machines.
