IBM 7094 at Columbia in 1965

some time between 1964 and 1968, operator John Szallasi at the console. The
IBM 709x series are the 36-bit machines on which LISP was developed; its
18-bit halfwords were perfect for CARs and CDRs. This is the machine that
inspired DEC's first 36-bit machine, the PDP-6, which was followed by the
PDP-10 and DEC-20.
Here are some other, non-Columbia IBM 7094 images; click the first
one to enlarge, the others are already shown full-size.

Views of the IBM 7094 at MIT about 1962.
The MIT 7094
machine is running MIT's Compatible Time Sharing System (CTSS),
arguably
the first timesharing system, which was later countered by MIT's PDP-10
based Incompatible Timesharing System (ITS).
