What happened September 1971 AD

In September 1973, President Nixon said, "Oil without a market, as Mr. Mossadegh learned many, many years ago, does not do a country much good", referring to the 1951 nationalization of the Iranian oil industry, but between October 1973 and February 1974 the OPEC countries raised by posted price fourfold to nearly $12. Because oil was priced in dollars, oil producers' real income decreased when the dollar started to float free of the old link to gold. In September 1971, OPEC issued a joint communiqué stating that from then on, they would price oil in terms of a fixed amount of gold.

The TMS1802NC was announced September 17, 1971 and implemented a four-function calculator. The TMS1802NC, despite its designation, was not part of the TMS 1000 series; it was later redesignated as part of the TMS 0100 series, which was used in the TI Datamath calculator. Although marketed as a calculator-on-a-chip, the TMS1802NC was fully programmable, including on the chip a CPU with an 11-bit instruction word, 3520 bits (320 instructions) of ROM and 182 bits of RAM.

However, 19 September 1971 was chosen as the official date of the formation of the party to coincide with the Pontianak Conference, which had been held on 17–19 September 1965.

OPEC directs members to negotiate price increases to offset the devaluation of the U.S. dollar.
