RM 380Z (Light Blue Case)

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.
It used a Z80 microprocessor and had up to 56 KiB 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 high-resolution graphics board.
The 380Z was sold mainly to schools in the UK, with some also sold to industry. In 1979 a dual 8-inch disk system with 56 KiB of memory cost £3266, and a 16 KiB cassette-based system cost £965 (excluding VAT).
  
The 380Z was packaged in a large, black, 19-inch wide, rectangular metal case containing the power supply, a number of printed circuit boards and the optional 5¼-inch floppy disk drives. Early versions were contained in a light blue metal case with a white front and only had a cassette interface; only a small number of these were made. Our unit is one those early versions. The keyboard was separate and came in a tough metal case.
 
The system used a passive bus architecture with no motherboard – all electronics were contained on a number of cards interconnected by ribbon cable. The only microprocessor offered was a 4 MHz Z80A.
