Snippet from Wikipedia: Altair 8800

The Altair 8800 is a microcomputer designed in 1974 by Micro Instrumentation and Telemetry Systems (MITS) and based on the Intel 8080 CPU. It was the first commercially successful personal computer. Interest in the Altair 8800 grew quickly after it was featured on the cover of the January 1975 issue of Popular Electronics and was sold by mail order through advertisements there, in Radio-Electronics, and in other hobbyist magazines. The Altair 8800 had no built-in screen or video output, so it would have to be connected to a serial terminal (such as a VT100-compatible terminal) to have any output. To connect it to a terminal a serial interface card had to be installed. Alternatively, the Altair could be programmed using its front-panel switches.

According to the personal computer pioneer Harry Garland, the Altair 8800 was the product that catalyzed the microcomputer revolution of the 1970s. The computer bus designed for the Altair became a de facto standard in the form of the S-100 bus, and the first programming language for the machine was Microsoft's founding product, Altair BASIC.

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.

Micro Instrumentation and Telemetry Systems, Inc. (MITS), was an American electronics company founded in Albuquerque, New Mexico that began manufacturing electronic calculators in 1971 and personal computers in 1975.

Ed Roberts and Forrest Mims founded MITS in December 1969 to produce miniaturized telemetry modules for model rockets such as a roll rate sensor. In 1971, Roberts redirected the company into the electronic calculator market and the MITS 816 desktop calculator kit was featured on the November 1971 cover of Popular Electronics. The calculators were very successful and sales topped one million dollars in 1973. A brutal calculator price war left the company deeply in debt by 1974.

Roberts then developed the first commercially successful microcomputer, the Altair 8800, which was featured on the January 1975 cover of Popular Electronics. Hobbyists flooded MITS with orders for the $397 computer kit. Paul Allen and Bill Gates saw the magazine and began writing software for the Altair, later called Altair BASIC. They moved to Albuquerque to work for MITS and in July 1975 started Microsoft.

MITS's annual sales had reached $6 million by 1977 when they were acquired by Pertec Computer. The operations were soon merged into the larger company and the MITS brand disappeared. Roberts retired to Georgia where he studied medicine and became a small town medical doctor.
