This is a matter of historical record, AIUI. http://forum.6502.org/viewtopic.php?t=1892 There's a little more here: http://www.theregister.co.uk/2012/05/03/unsung_heroes_of_tech_arm_creators_sophie_wilson_and_steve_furber/ In essence, Wilson designed it and Furber implemented it. Wilson knew 6502 inside-out and had been designing 6502 systems while still a student, before Acorn existed, so it inspired the ARM ISA, rather than ARM actually being based on it. 6502 is widely held as being, if not actually RISC, then at least RISC-like, or as Brits put it, RISCy. http://everything2.com/title/6502 https://news.ycombinator.com/item?id=11703717 -- Liam Proven • Profile: http://lproven.livejournal.com/profile Email: lpro...@cix.co.uk • GMail/G+/Twitter/Flickr/Facebook: lproven MSN: lpro...@hotmail.com • Skype/AIM/Yahoo/LinkedIn: liamproven Cell/Mobiles: +44 7939-087884 (UK) • +420 702 829 053 (ČR)
