The Altair 8800 is a microcomputer designed in 1974 by MITS and based on the Intel 8080 CPU. [2] Interest grew quickly after it was featured on the cover of the January 1975 issue of Popular Electronics [3] and was sold by mail order through advertisements there, in Radio-Electronics, and in other hobbyist magazines.
Three microcomputer systems frequently associated with the first wave of commercially successful 8-bit home computers: The Commodore PET 2001, the Apple II, and the TRS-80 Model 1. By the early 2000s, everyday use of the expression "microcomputer" (and in particular "micro") declined significantly from its peak in the mid-1980s. [7]
The Sol-20 was the first fully assembled microcomputer with a built-in keyboard and television output, [a] what would later be known as a home computer. The design was the integration of an Intel 8080-based motherboard, a VDM-1 graphics card, the 3P+S I/O card to drive a keyboard, and circuitry to connect to a cassette deck for program storage.
France had produced the first microcomputer. A year would pass before the first North American microcomputer, SCELBI, was advertised in the March 1974 issue of QST, an amateur radio magazine. [13] Indeed, INRA was originally planning to use PDP-8 computers for process control, but the Micral N could do the same for a fifth of the cost.
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals.
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 at International Business Machines (IBM), directed by William C. Lowe and ...
Mary Allen Wilkes working on the LINC at home in 1965; thought to be the first home computer user The 1974 MITS Altair 8800 home computer (atop extra 8-inch floppy disk drive): one of the earliest computers affordable and marketed to private / home use from 1975, but many buyers got a kit, to be hand-soldered and assembled.
