in the Watson Laboratory program library, in the days when programs were
wired onto plugboards. Pictured: a pair of IBM Type 602-A Calculating
, which dates the picture between 1948 (when the 602-A was
released) and 1959 (when Eric left the Lab).
The larger machine to the right might be part of an IBM
for a photo of Eckert and Thomas in the same spot.
