  In theory.  In practice, many P-System programs made
calls to
 platform-specific extensions to the language in question, 
 linking against a library of a dozen or so routines for doing
 non-standard subroutines written in machine code: block
 memory moves, disk block reads, etc.  I don't think those
 were ever standardized between platforms.   
...
  You can't take the average clone of Pacman or
whatever from an 
 Apple II P-System and run it on another system unless it was 
 completely pure - poking video memory ain't pure. 
At some degree - there have been a lot of Units available
on different platforms. And as everywhere in these old
days the ctr controll codes had more impact an porting
than anything else. In fact I used the p-system several
times for cross platform developments in the early 80s.
Even for my first app on the IBM-PC - The next few apps
where developed with Turbo Pascal on the APPLE ][+ using
CP/M and recompiled on the PC. I withstand the IBM for
almost two years ...

  See my web page for a history of the UCSD P-System.

Hmm letmesee... only Pascal ?
What about the otherlanguages ?

...
  I'd love to get a Microengine.  
Ibet there are still some out there.
