The microprocessor led to the development of microcomputers and personal computers, and the microcomputer revolution. The first microcomputers, based on microprocessors, were developed during the early 1970s. DEC agreed to contribute more than 300 terminals, 1600 microcomputers, 63 minicomputers, and five employees. He states we will progress from stand-alone microcomputers and decentralized mainframes towards pervasive computing. More than 200 terminals, microcomputers, and workstations are located here. YMODEM is a file transfer protocol used between microcomputers connected together using modems. Both tape drives and floppy disk drives were common on early microcomputers. A number of releases for 8-bit microcomputers followed. One example was the Microsoft BASIC interpreter supplied with most microcomputers that ran VisiCalc. The product was CIS COBOL, a standard-compliant COBOL implementation for microcomputers. The Altair 8800 was one of the first microcomputers intended for home use. This is a list of early microcomputers sold to hobbyists and developers. They were the first microcomputers with an operating system. Widely distributed, available on many early microcomputers. Many of the earliest microcomputers implemented the Kansas City standard for digital data storage.
