    More than I care to, but probably fewer than you'd want.  It was
    the first p-machine whose details I learned -- for a compiler-writing
    class, as a matter of fact, where the teacher expected our compilers
    to generate executing programs.  And I must say that emitting code for it
    was quite straightforward.  We did no optimisation, of course,
    but then p-code is already pretty tight.

    There are some details of it that I can still remember, but you'd
    probably be better off first trying Western Digital, to see if they
    still have copies of their documentation available.  I don't think
    that, at the time, the Internal Architecture Guide was yet a separate
    document.  Rather, I think it was its own section in the MicroEngine
    manual.  Of course, this was a number of years ago, so they may well
    have none available.
