Bendix G-20

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. Word 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.

Memory locations 1 through 63 were used as index registers. One hundred and ten instructions were in the instruction set. The CPU included integral block I/O and interrupt facilities. Multiply time was 51-63 microseconds, and divide time was 72-84 microseconds. Basic memory cycle time was 6 microseconds.

A special programming language, called 20-GATE, was developed for the G-20.

G-20 major economies

The Group of Twenty (also known as the G-20 or G20) is an international forum for the governments and central bank governors from 20 major economies. The members include 19 individual countries—Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, South Korea, Mexico, Russia, Saudi Arabia, South Africa, Turkey, the United Kingdom and the United States—along with the European Union (EU). The EU is represented by the European Commission and by the European Central Bank. The G-20 was founded in 1999 with the aim of studying, reviewing, and promoting high-level discussion of policy issues pertaining to the promotion of international financial stability. It seeks to address issues that go beyond the responsibilities of any one organization. Collectively, the G-20 economies account for around 85% of the gross world product (GWP), 80% of world trade (or, if excluding EU intra-trade, 75%), and two-thirds of the world population. The G-20 heads of government or heads of state have periodically conferred at summits since their initial meeting in 2008, and the group also hosts separate meetings of finance ministers and central bank governors.
