Advanced Digital Corporation
Advanced Digital Corporation (ADC) was a privately owned American computer company based in California, active from the 1980s to the 1990s. The company was founded by 1980 by a group of engineers, in order to market their single-user and multi-user expansion cards and peripherals for S-100–based computers. In 1983, ADC introduced a pair of their own S-100 computers, the Super Six and the Super Star. In 1984, they made the pivot to production of expansion cards for the IBM Personal Computer, with one (the PC II, co-produced by Link Technologies of Fremont) allowing the IBM PC to be used as a multi-user platform, with as many as 32 concurrent users. Toward the late 1980s, they introduced their own 386SX-based PC compatible systems under the PowerLite name, to critical acclaim in the tech press. ADC was initially based in Garden Grove, California, employing 35 by mid-1983. In late 1983, they moved to Huntington Beach Huntington Beach is a seaside city in Orange County in Sou ...

Garden Grove, California
Garden Grove is a city in northern Orange County, California, United States, located just southwest of Disneyland (located in Anaheim, CA). The population was 171,949 at the 2020 census. State Route 22, also known as the Garden Grove Freeway, passes through the city in an east–west direction. The western portion of the city is known as West Garden Grove. History 19th century Garden Grove was founded by Alonzo Cook in 1874. A school district and Methodist church were organized that year. It remained a small rural crossroads and farming community until the arrival of the Pacific Electric Railroad in 1905. The rail connection helped the town prosper with the influx of tourists, visitors and eventually settlers, and it was noted for its crops of oranges, walnuts, chili peppers and later strawberries. 20th century In 1933, much of the town's central business district was destroyed by the Long Beach earthquake, and one person was killed at the high school. The post-World Wa ...

Multi-user Software
Multi-user software is computer software that allows access by multiple users of a computer. Time-sharing systems are multi-user systems. Most batch processing systems for mainframe computers may also be considered "multi-user", to avoid leaving the CPU idle while it waits for I/O operations to complete. However, the term " multitasking" is more common in this context. An example is a Unix or Unix-like system where multiple remote users have access (such as via a serial port or Secure Shell) to the Unix shell prompt at the same time. Another example uses multiple X Window sessions spread across multiple terminals powered by a single machine - this is an example of the use of thin client. Similar functions were also available in a variety of non-Unix-like operating systems, such as Multics, VM/CMS, OpenVMS, MP/M, Concurrent CP/M, Concurrent DOS, FlexOS, Multiuser DOS, REAL/32, OASIS, THEOS, PC-MOS, TSX-32 and VM/386. Some multi-user operating systems such as Windows versions fr ...

S-100 Bus
The S-100 bus or Altair bus, IEEE 696-1983 ''(withdrawn)'', is an early computer bus designed in 1974 as a part of the Altair 8800. The bus was the first industry standard expansion bus for the microcomputer industry. computers, consisting of processor and peripheral cards, were produced by a number of manufacturers. The bus formed the basis for homebrew computers whose builders (e.g., the Homebrew Computer Club) implemented drivers for CP/M and MP/M. These microcomputers ran the gamut from hobbyist toy to small business workstation and were common in early home computers until the advent of the IBM PC. Architecture The bus is a passive backplane of 100-pin printed circuit board edge connectors wired in parallel. Circuit cards measuring 5 × 10-inches serving the functions of CPU, memory, or I/O interface plugged into these connectors. The bus signal definitions closely follow those of an 8080 microprocessor system, since the Intel 8080 microprocessor was the first ...

IBM Personal Computer
The IBM Personal Computer (model 5150, commonly known as the IBM PC) is the first microcomputer released in the IBM PC model line and the basis for the IBM PC compatible de facto standard. Released on August 12, 1981, it was created by a team of engineers and designers directed by Don Estridge in Boca Raton, Florida. The machine was based on open architecture and third-party peripherals. Over time, expansion cards and software technology increased to support it. The PC had a substantial influence on the personal computer market. The specifications of the IBM PC became one of the most popular computer design standards in the world. The only significant competition it faced from a non-compatible platform throughout the 1980s was from the Apple Macintosh product line. The majority of modern personal computers are distant descendants of the IBM PC. History Prior to the 1980s, IBM had largely been known as a provider of business computer systems. As the 1980s opened, th ...

Fremont, California
Fremont is a city in Alameda County, California, United States. Located in the East Bay region of the Bay Area, Fremont has a population of 230,504 as of 2020, making it the fourth most populous city in the Bay Area, behind San Jose, San Francisco, and Oakland. It is the closest East Bay city to the high-tech Silicon Valley network of businesses, and has a strong tech industry presence. The city's origins lie in the community that arose around Mission San José, founded in 1797 by the Spanish under Padre Fermín Lasuén. Fremont was incorporated on January 23, 1956, when the former towns of Mission San José, Centerville, Niles, Irvington, and Warm Springs unified into one city. Fremont is named after John C. Frémont, a general who helped lead the American Conquest of California from Mexico and later served as Military Governor of California and then U.S. Senator. History Early history The recorded history of the Fremont area began on June 6, 1797, when Mission San José ...

IBM PC Compatible
IBM PC compatible computers are similar to the original IBM PC, XT, and AT, all from computer giant IBM, that are able to use the same software and expansion cards. Such computers were referred to as PC clones, IBM clones or IBM PC clones. The term "IBM PC compatible" is now a historical description only, since IBM no longer sells personal computers after it sold its personal computer division in 2005 to Chinese technology company Lenovo. The designation "PC", as used in much of personal computer history, has not meant "personal computer" generally, but rather an x86 computer capable of running the same software that a contemporary IBM PC could. The term was initially in contrast to the variety of home computer systems available in the early 1980s, such as the Apple II, TRS-80, and Commodore 64. Later, the term was primarily used in contrast to Apple's Macintosh computers. These "clones" duplicated almost all the significant features of the original IBM PC architectu ...

Computer Companies Established In 1980
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (computation). Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots. Computers are at the core of general-purpose devices such as personal computers and mobile devices such as smartphones. Computers power the Internet, which links billions of computers ...
