Research Machines 380Z : ウィキペディア英語版 | Research Machines 380Z
The Research Machines 380Z (often called the RML 380Z or RM 380Z) was an early 8-bit microcomputer produced by Research Machines Limited in Oxford, England, from 1978 to 1985. ==Description== The 380Z used a Z80 microprocessor (hence the name) with up to 56 KB of user RAM. When fitted with an optional floppy disk drive the system ran the CP/M operating system. The basic system came with a text-only monochrome video card, which could be enhanced with a 320×192 high-resolution graphics board. Aided by a British government subsidy to schools for half of the price the 380Z was sold mainly to educational institutions in the United Kingdom, with some also sold to industry. In 1979 a dual 8-inch disk system with 56 KB of memory cost £3266, and a 16 KB cassette-based system cost £965 (excluding VAT).
