On 30 July 1969 IBM announced the IBM System/3 in the
United States.
It is today fourty year ago that IBM offered the first medium-sized
computer for the small business companies. The System/3 was not
compatible with the System/360, as it featured a complete new
architecture. It also featured a complete new punch card format, which
was a small revolution within IBM.
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
bytes?
