[Simh] Question about card readers.

[khandy21yo]

I once saw a IBM punch card that was small as a playing card, had three rows of 8? Punches, and held more than 80 characters. The operators actually used them as playing cards.

  And UNIVAC had a 90 column card for a long time.  It looked something like a traditional Hollerith card but had round punches and two rows of six bit characters.
