MAA (predecessor of Digital Research) defined together with Intel a new system-programming language called PL/M (Programming Language for Microcomputers) to replace assembly-language programming for Intel's 8-bit processors

1972

Pong video game is a success.

1972

The first implementation of PROLOG (Programming in Logic) developed at University of Aix-Marselle. It's the preferred language for the 5-th generation of machines. It's a descriptive and declarative language.

1972

Dennis Ritchie from Bells Labs. produces C, a programming language derived from BCLP. The most popular language for professionals, not recommended for beginners.

1972

FORTH appears, a medium-level language which uses a small numbers of very brief instruction words. designed for telescope control will become the standard language used in astronomy.

1972

Pioneer 10 spacecraft used the first Intel 4004 microprocessor.

1972

Unix is rewritten in C by Kernel.

1972

Texas Inst. announced their first microprocessor.

1972

Intel ships the 8008 microprocessor, a 8-bit version of 4004.

1973

Unix version 4 allows C programming languages

1973 Bob Metcalfe invented the Ethernet, the network design that allows computers to communicate to each other over a local area network (LAN)

1973

Internet consists of 25 computers.

1973

ARPANet becomes operational.

1973

Digital develops DEC Data Communication Message Protocol (DDCMP) as a standard for its future computer-to-computer communications.

1973

In December Intel's new microprocessor 8080 is used in first microcomputer MITS's Altair.

1974

Unix version 5.

1974

1974

Digital announces LA36 DECwriter II which will became the market standard.

1974

Federico Faggin, a top employer of Intel, founded Zilog in December.

1975

Unix version 6.

1975

Bill Gates and Paul Allen write a version of BASIC that they sell to MITS who used it in Altair microcomputers. It was a ROM based interpreted BASIC which will become known as Microsoft BASIC.

1975

Altair 8800 becomes the first personal computer ( microcomputer) on the market. Over 2000 sold by end of the year. It cost $395 but up to $2000 worth of peripherals were needed to make it go. Used Intel 8080 microprocessor and 256 bytes memory.
