The 8086 (also called iAPX 86) is a 16-bit microprocessor chip designed by Intel between early 1976 and June 8, 1978, when it was released. The Intel 8088, released July 1, 1979,[4], is a slightly modified chip with an external 8-bit data bus (allowing cheaper and fewer supporting ICs). It is notable as the processor used in the original IBM PC design. The 8086 gave rise to the x86 architecture, which eventually became Intel’s most successful processor line. On June 5, 2018, Intel released a limited-edition CPU celebrating the 40th anniversary of the Intel 8086, called the Intel Core i7-8086K.

USR was founded in 1976 in Chicago, Illinois (and later moved to Skokie, Illinois) by a group of entrepreneurs, including Casey Cowell, who served as CEO for most of the company’s history, and Paul Collard, who designed modems into the mid-1980s. The company name is a reference to the fictional company U.S. Robots and Mechanical Men, which featured prominently in the works of Isaac Asimov.

The Fairchild Channel F, short for “Channel Fun”, was the first video game console to use ROM cartridges, instead of having games built-in, and the first console to use a microprocessor. It was released by Fairchild Camera and Instrument in November 1976 across North America at a retail price of US$169.95 (equivalent to $763.58 in 2019). It was launched as the “Video Entertainment System”, but when Atari, Inc. released its Video Computer System the next year, Fairchild rebranded their machine as “Channel F” while keeping the Video Entertainment System descriptor. The Fairchild Channel F achieved only about 350,000 units before Fairchild sold the technology to Zircon International in 1979, trailing well behind the VCS. The system was discontinued in 1983.

XMODEM is a simple file transfer protocol developed as a quick hack by Ward Christensen for use in his 1977 MODEM.ASM terminal program. It allowed users to transmit files between their computers when both sides used MODEM. Keith Petersen made a minor update to always turn on “quiet mode”, and called the result XMODEM.

XMODEM, like most file transfer protocols, breaks up the original data into a series of “packets” that are sent to the receiver, along with additional information allowing the receiver to determine whether that packet was correctly received. If an error is detected, the receiver requests that the packet be re-sent. A string of bad packets causes the transfer to abort.

XMODEM became extremely popular in the early bulletin board system (BBS) market, largely because it was simple to implement. It was also fairly inefficient, and as modem speeds increased, this problem led to the development of a number of modified versions of XMODEM to improve performance or address other problems with the protocol. Christensen believed his original XMODEM to be “the single most modified program in computing history”

Microsoft officially dropped the hyphen in Micro-soft and trademarks the Microsoft name on November 26, 1976.

1976 in Software:

Mesa is a programming language developed in the late 1970s at the Xerox Palo Alto Research Center in Palo Alto, California, United States. The language name was a pun based upon the programming language catchphrases because Mesa is a “high-level” programming language.

Smalltalk is an object-oriented, dynamically typed reflective programming language. Smalltalk was created as the language underpinning the “new world” of computing exemplified by human-computer symbiosis. It was designed and created in part for educational use, specifically for constructionist learning, at the Learning Research Group (LRG) of Xerox PARC.

20th Century 1975

The January 1975 issue of Popular Electronics comes out, proudly announcing the “World’s First Minicomputer Kit to Rival Commercial Models…”, the Altair 8800. Altair had hoped to clear a few hundred orders to pay for the actual purchase of the needed parts to sell, but instead, the system was so popular from the article that it received over four hundred orders in one afternoon. The cover’s image was a mock-up due to the working model being lost en route to Popular Electronics.

The first microcomputer implementation of BASIC by Bill Gates and Paul Allen was written for the MITS Altair, which led to Microsoft’s formation later in the year.

1975 Software:

Altair BASIC is a discontinued interpreter for the BASIC programming language that ran on the MITS Altair 8800 and subsequent S-100 bus computers. It was Microsoft’s first product (as Micro-Soft), distributed by MITS under a contract. Altair BASIC was the start of the Microsoft BASIC product range.

Ikarus is a type of design and production software developed by URW foundry for converting existing typefaces and logos into digital format for computer-driven printing, plotting, and sign-cutting devices.

Appearing in Version 7, Unix was originally written by Stephen C. Johnson of Bell Labs in 1975. Douglas McIlroy later improved its accuracy, performance, and memory use and described his work and spell in general in his 1982 paper “Development of a Spelling list.”

1975 Game Companies:

Cinematronics Incorporated was an arcade game developer that primarily released vector graphics games in the late 1970s and early 1980s. While other companies released games based on raster displays, early in their history, Cinematronics and Atari, Inc. released vector-display games, which offered a distinctive look and a greater graphic capability (at the time), at the cost of being only black and white (initially). Cinematronics also published Dragon’s Lair in 1983, the first major LaserDisc video game.

Square Enix Holdings Co., Ltd. is a Japanese video game holding company and entertainment conglomerate, best known for its Final Fantasy, Dragon Quest, and Kingdom Hearts role-playing video game franchises, among numerous others.

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.

March 29, 1974: Mariner 10 becomes the first spacecraft to fly by Mercury.

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).

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.
