Yep, about that size. What made no sense to me is that each column
is BA8421 - 6 bits. This long after IBM had settled on 8-bit EBCDIC.
Most installations had standardized on the 80 column card, so it
didn't make much of a splash unless you were a System/3 installation.

I haven't
been following this thread very closely, but I trust
someone has mentioned the 96 column System/3 mini-card:
http://homepages.cwi.nl/~dik/english/codes/96col.html
Holds more characters, but less data than a standard 80 column card.
That was the one roughly the size of a 3.5" floppy, wasn't it? I worked at a
place once that used those...
