> It's like [6502] hit the spot, and stopped growing. Indeed. In fact, Acorn played around with a couple of successor candidates like national semiconductor 32016 (and even Intel 80186) using the BBC micro's Tube interface before they finally have up and developed the ARM chip. In a sense, ARM (initially Acorn RISC machine) is "the true" 6502 successor. Having done assembly on both BASIC II and V (on Archimedes) the legacy in arm2 Isa was quite evident.
