caption_attribution_description: English: A Commodore 64, an 8-bit home computer introduced in 1982 by Commodore International. Its low retail price and easy availability led to the system becoming the market leader for three years. It remains the best-selling single personal computer model of all time.
context_page_description: A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit. It includes a microprocessor, memory and minimal input/output circuitry mounted on a single printed circuit board. Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive. Many microcomputers are also personal computers.
  The abbreviation micro was common during the 1970s and 1980s, but has now fallen out of common usage.
context_section_description: A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit (CPU). It includes a microprocessor, memory and minimal input/output (I/O) circuitry mounted on a single printed circuit board (PCB). Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive (though indeed present-day mainframes such as the IBM System z machines use one or more custom microprocessors as their CPUs). Many microcomputers (when equipped with a keyboard and screen for input and output) are also personal computers (in the generic sense).
  The abbreviation micro was common during the 1970s and 1980s, but has now fallen out of common usage.
