Our customer support team



Paul Walker


Having worked for original British manufacturers of computers: Elliott Brothers, Ferranti, ICL, and Computer Technology, Paul Walker joined Inmos, where he championed the communication links of the Transputer.
He founded 4Links in 1993 to promote the link technology, and established a market in the space industry. He is grateful to his colleagues and to the many customers and suppliers of 4Links.
He hopes that he is worthy of ESA’s citation of ‘The Grandfather of SpaceWire’.
