Wasn't one of the problems with the 96 column
mini-card that it used
only 6 punch positions per character on an otherwise 8-bt machine?
For those of you having used the system, was there such a thing as
column binary on the little cards? If so, was it 4 columns = 3

The extra 2 bits occupied the printable area of the card on top.
makeing each card 96 bytes.
