GE-600 series

Mainframe Family

The GE-600 series is a family of 36 bit mainframe computers that General Electric built from technology developed for military projects in 1959 and released commercially in 1963. The line is remembered chiefly for the operating systems it ran: the Dartmouth Time-Sharing System, an early system for interactive computing, and especially Multics, the ambitious operating system developed jointly by General Electric, MIT and Bell Labs from 1964, for which a specialized GE 645 variant added an eighteen bit memory segment to the standard eighteen bit address to support virtual memory. General Electric left the mainframe business in 1970, selling the line to Honeywell, which continued developing it as the Honeywell 6000 series into the 1990s; the GE-600's Multics work also fed directly into the early development of Unix.
