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’.



Spencer Saunders

General Manager

Before joining 4Links Spencer previously worked at ARM initially developing IP, then managing the development platforms group for prototyping and validation and finally directing their hardware acceleration capabilities for IP validation. He then moved to Mentor Graphics to architect and managing their new FPGA prototyping hardware development.


This has given him the skills to take a concept, create a business case, extract requirements, then manage the engineering and operations teams to put it into production.
