a Univac 1108 (replacing the preceding UNIVAC 1107), 36 bit, ones' complement machine. The company was sold in 1977 to Robert G. Benson in Beachwood, Ohio becoming Ecocenters Corporation.
Project Logos, under ARPA contract, was begun within the department on a DEC System-10 (later converted to TENEX (BBN) in conjunction with connection to the ARPANET) to develop a computer-aided computer design system. This system consisted in a distributed, networked, graphics environment, a control and data flow designer and logic (both hardware and software) analyzer. An Imlac PDS-1 with lightpen interrupt was the main design workstation in 1973, communicating with the PDP-10 over a display communications protocol written by Don Huff as a Master Thesis and implemented on the Imlac by Ted Brenneman. Graphics and animation became another departmental focus with the acquisition of an Evans & Sutherland LDS-1 (Line Drawing System-1), which was hosted by the DEC System-10, and later with the acquisition of the stand-alone LDS-2.
