B&W image of Juril Semkiw sitting at the SILLIAC console. In the background are the computer cabinets. In the foreground is a printer. The SILLIAC (Sidney version of the Illinois Automatic Computer), an early computer built by the University of Sydney, Australia, was based on the ILLIAC and ORDVAC computers developed at the University of Illinois, which in turn were based on the IAS architecture developed by John von Neumann.
