Actually, there were P-system implementations for all
sorts of machines
 (not suprisingly -- the idea was that much of the system was portable).
 There was certainly a PDP11 version. And I remember reading about a
 version for the PC (along with the complaint that it could only use
 floppy drives, and would ignore the hard disk in a PC/XT system)

One of the more interesting was the bootleg that floated past me
years ago of the P-System for DEC PDT11/150's.
A lot of fun running it on VT100's.  When I saw Turbo Pascal
I realized where Borland got the IDE for Pascal idea.
