From a news release about Honeywell’s Forty-Ton Mainframe :
The Datamatic 1000 was the first electronic computer system produced by Honeywell. An operator monitored the 40 tons of equipment from the master control console at this installation at Michigan Blue Cross-Blue Shield in Detroit. This first-generation vacuum-tube system was used by the medical and health insurance company from 1958 to 1964.
Weik’s Third Survey of Computing Systems (1961) states that the Datamatic 1000 contained 3,600 vacuum tubes, had 2 Kwords of core store, occupied an area of 4,500 square feet, and consumed 95 Kw of power. With peripherals, it cost about $2 million.
