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.

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).
