High Quality Content by WIKIPEDIA articles! The Bendix G-20 computer was introduced in 1961 by the Bendix Corporation, Computer Division, Los Angeles, California. The G-20 followed the highly successful G-15 vacuum tube computer. Bendix sold its computer division to Control Data Corporation in 1963, effectively terminating the G-20. The G-20 system was a general purpose mainframe computer, constructed of transistorized modules and core memory. Memory size was 32 bits, plus parity. Up to 32k words of memory could be used. Single and Double precision floating point were allowed, as well a custom scaled format, called Pick-a-Point. A special form of the pick-a-point allowed an integer.
