As usual you have all helped me to solve the mystery. I'm sure that these are the magnetic cards used in the IBM MC/ST. The next question is, is there anyone out there that has some way of reading these or getting the information off of the cards into electronic or print form? How do I store and preserve these or is it even worth keeping these cards? My archivist instinct tells me not to throw something like this away even if I can't find a machine to read the cards. ~~~~~~~~~~~~~~~~~~~~~~ Christina J.
