A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a single integrated circuit microprocessor. The computer also includes memory and input/output (I/O) circuitry together mounted on a printed circuit board (PCB). Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors such as the MOS Technology 6502, Zilog Z80, and Intel 8088. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive.
