I also chatted with Mr. Richards for a while, after porting BCPL to the GP2X handheld 'underground' gaming machine, and using BCPL to emulate an EDSAC on which I wanted to run XOX, thus claiming the title of 'oldest title to be ported to the GP2X', for a while.
Mr. Richards got himself a GP2X after a while, and then saw how folks were porting BCPL all over the place, and I think he kind of got a big kick out of that .. we fell out of touch, but it was really a worthwhile effort to port BCPL like that, and attract the attention of the master ..
