20th Century: 1974

The Intel 8080 (“eighty-eighty”) is the second 8-bit microprocessor designed and manufactured by Intel. On April 1, 1974, it first appeared and was an extended and enhanced variant of the earlier 8008 design, although without binary compatibility. The initial specified clock rate or frequency limit was 2 MHz. With common instructions using 4, 5, 7, 10, or 11 cycles, this meant that it operated at a typical speed of a few hundred thousand instructions per second. A faster variant, 8080A-1 (Sometimes called the 8080B), became available later with a clock frequency limit of 3.125 MHz.

The 6800 (“sixty-eight hundred”) is an 8-bit microprocessor designed and first manufactured by Motorola in 1974. The MC6800 microprocessor was part of the M6800 Microcomputer System, including serial and parallel interface ICs, RAM, ROM, and other support chips. A significant design feature was that the M6800 family of ICs required only a single five-volt power supply at a time when most other microprocessors required three voltages. The M6800 Microcomputer System was announced in March 1974 and was in full production by the end of that year.

Telenet was an American commercial packet-switched network that went into service in 1975. It was the first FCC-licensed public data network in the United States. Various commercial and government interests paid monthly fees for dedicated lines connecting their computers and local networks to this backbone network. Free public dialup access to Telenet, for those who wished to access these systems, was provided in hundreds of cities throughout the United States. The first Internet Service Provider (ISP).

Digital Research was founded by Gary Kildall in 1974.

Foxconn was founded in 1974. Foxconn manufactures electronic products for major American, Canadian, Chinese, Finnish, and Japanese companies. Notable products manufactured by Foxconn include the BlackBerry, iPad, iPhone, iPod, Kindle, Nintendo 3DS, Nintendo Switch, Nintendo Switch Lite, Nokia devices, Xiaomi devices, PlayStation 3, PlayStation 4, Wii U, Xbox 360, Xbox One,and several CPU sockets, including the TR4 CPU socket on some motherboards. As of 2012, Foxconn factories manufactured an estimated 40% of all consumer electronics sold worldwide.

CLU is a programming language created at the Massachusetts Institute of Technology (MIT) by Barbara Liskov and her students between 1974 and 1975. While it did not find extensive use, it introduced many widely used features and are seen as steps in developing object-oriented programming (OOP).

GRASS (GRAphics Symbiosis System) is a programming language created to script 2D vector graphics animations. GRASS was similar to BASIC in syntax but added numerous instructions for specifying 2D object animation, including scaling, translation, and rotation over time. These functions were directly supported by the Vector General 3D graphics terminal GRASS was written for. It quickly became a hit with the artistic community who experimented with the new medium of computer graphics. It is most famous for Larry Cuba’s use to create the original “attacking the Death Star will not be easy” animation in Star Wars (1977).

BATCH-11/DOS-11, also known as DOS-11, is a discontinued operating system by Digital Equipment Corporation (DEC) of Maynard, Massachusetts. The first version of DOS-11 (V08-02) was released in 1970 and was the first operating system to run on the Digital PDP-11 minicomputer. DOS-11 was not known to be easy to use even in its day and became much less used in 1973 with the release of the RT-11 operating system.
