  • The Inmos Legacy - transputer links and SpaceWire
    After reading https://forums.theregister.com/forum/all/2022/05/06/pi_pico_transputer_code/, I was looking for information related to transputers and found this page.

    The point-to-point technology to link transputers was formalised in the IEEE 1355 standard. This was further developed under the ESA into SpaceWire, which is now designed into a number of space missions under development in Europe, the USA and Japan. A key player in developing SpaceWire was Paul Walker from the transputer team whose company, 4Links, is now selling SpaceWire test equipment.

    XMOS mentioned on the page can be found on https://www.xmos.ai
