Nascom emerged from John Marshall's Lynx Electronics and helped establish Britain's early microcomputer-kit market. Marshall commissioned engineer Chris Shelton to design an affordable Z80-based computer, and the resulting Nascom 1 was introduced in 1977 as a single-board machine for enthusiasts, education and development work.
The improved Nascom 2 followed with more memory and a more capable design, supported by expansion boards, cases and third-party software. Financial difficulties eventually led to Nascom becoming part of Lucas Industries, but its open, expandable computers gave many British users and engineers their first practical experience with microprocessors.
