I joined Inmos in 1982 and worked on the transputer CAD system as part of a small team led by Miles Chesney. One of the things that seems remarkable, in retrospect, is the fact that we (the Microprocessor Design Group) designed not only the end product (processor, language and development system) but all of the tools used to design them: CAD system, graphics workstations, networking software, text editors and so on. I can't recall a single case of a software (or hardware) tool that was externally sourced. Whether this was an admirable trait is another question but it certainly made for an exciting life.
