Haven't been following the thread, so I don't know if some of this has been
said.
I think I have C code (ca-1985) that implements a p-code pascal->pcode compiler
and a pcode interpreter under unix. It's certainly not the full P-system,
though.
You can get Pascal source for an early compiler and interpreter on
http://www.threedee.com/jcm/psystem/index.html
You can also get an emulator there.
