"Will you be interviewing Sophie Wilson? I read somewhere that she modeled the entire ARM command set in BBC BASIC."
Steve Furber did. Apparently (according to the talk he did for WROCC, which looks similar to what is planned for Huddersfield next Sunday) he recently re-discovered the files on an old disc in his garage. ARM still consider them commercially valuable, however, so don't expect to see them released on the internet any time soon.
