Regency Systems R2C
The R2C was the color version of the 2nd Z80-based microcomputer produced by Regency Systems of Champaign, Illinois, the first being the RC1. The RC1 had a high resolution display and dual 8-inch floppy disk drives. It was essentially a standalone PLATO (computer system), PLATO environment, adapting the TUTOR (programming language), TUTOR language and environment. The company was founded by David Eades (real estate), David Eades, a real-estate agency owner, and Paul Tenczar, creator of the TUTOR (programming language), TUTOR language. The R2C supported an Ethernet network and a hard drive. The introduction of the IBM AT, with 16-bit processor, hard drive, and EGA display, sparked a change in direction for the company away from hardware.

Microcomputer
A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a 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. 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). An early use of the term "personal computer" in 1962 predates microprocessor-based designs. ''(See "Personal Computer: Computers at Companies" reference below)''. A "microcomputer" used as an embedded control system may have no human-readable input and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
