HP's operating systems implementation language seems to be based on ESPOL.

The microcoded machine concepts used in the B1600-1700 machines are more interesting. I think a *fast* chip level implementation might prove to be a possible general solution to the Pascal/Forth engine problems. -- George Robbins uucp: {unirot|tapa}!grr P.O.
