I remember the 90 column Univac format, but also remember that Univac 
at a very early date also offered 80 column compatibility.  Sometimes 
that meant selling a completely different computer system, not just 
peripherals (e.g. the SS 80 vs. the SS 90 systems).

I haven't been following this thread very closely, but I trust 
someone has mentioned the 96 column System/3 mini-card:

Holds more characters, but less data than a standard 80 column card.
