Agree 100%. I think that without Saxby there would be no Arm as we know it today.
IIRC Steve Furber and colleagues considered the licensing model and decided it would never work. Saxby made it work. All credit to him too for standing down before he overstayed his welcome and keeping out the limelight since.
Yes, re Sophie it was Firepath I think as per this presentation (2014).
