Yes and no.
Sophie Wilson, the best 6502 programmer ever, became disappointed with what she could do with the BBC Micro, and went off on her own to design a RISC processor that would do all the good things she liked about the 6502, and all the other things which she wished the 6502 could do.
So apparently the nice thing about 6502 was the simplicity of it, but they were determined to build something completely different (a RISC processor with no real architectural heritage from the 6502 itself):
I can still write in hex for [the 6502] - things like A9 (LDA #) are tattoed on the inside of my skull. The assembly language syntax (but obviously not the mnemonics or the way you write code) and general feel of things are inspirations for ARM's assembly language and also for FirePath's. I'd hesitate to say that the actual design of the 6502 inspired anything in particular - both ARM and FirePath come from that mysterious ideas pool which we can't really define (its hard to believe that ARM was designed just from using the 6502, 16032 and reading the original Berkeley RISC I paper - ARM seems to have not much in common with any of them!)
