UCSD P-system?
Now theres a name I haven't seen in a while.... 10 or so years ago I

up by a TV manufacturer. Anyway, the story goes that
the P-System was
considered by IBM along with CP/M for the PC. Don't know how much thuth
I was under the impression it was actually available for the 5150 PC, but
that it was never updated to handle hard drives (so pretty useless on a
5160 PC/XT).
there was to that but even in my time we had several
customers still
running P-System natively on a variety of hardware - AppleII, a
contemporary mini (can't remember which) at Norwich Union and some 68K
based (Stride?) systems.
The Sage II (and I assume Sage IV) are 68K machines that normally run the
P-system. I've never tried it (too many projects...), but the HP Pascal
for the 9000/200 machines looks remarkably like the P-system from the
manuals I've seen.
And of course the PERQ running the POS operating system had microcode
that interpretted something called Q-codes. This was remarkably similar
in concept (and architecture IIRC) to the P-system. It was just done
properly :-).
