The LINK 480Z was an 8-bit microcomputer produced by Research Machines Limited in Oxford, England, during the early 1980s.
The 480Z used a Z80 microprocessor with up to 256 KB of bank-switched RAM.[1] The system could be used as a stand-alone unit with cassette-based storage and the BASIC programming language run from ROM, or it could boot CP/NOS (a network version of CP/M) over a local area network from a file server. When fitted with an optional external floppy disk drive the system could boot the CP/M operating system directly.
The 480Z was sold mainly to the UK educational market as cassette-based system or as a diskless node which could be connected, via the proprietary CHAIN Network, to a Research Machines 380Z acting as a file server.
