As Monroe Systems is  still in business. Contact them, they might have an historian that could help you.

Also, there a brochure for sale on ebait.  There is a preview of 4 pages that supplies some general  info (for free)

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

I have a few reels of two-inch video tape which I've used to make crude magnetic cards for old HP desktop machines.
