I have an interpreter written in C for the version IV P-machine (on a
commercial basis).


I am not aware of any electronically available copies of the p-System
Internal Architecture Manual.


The original owners, Softech Microsystems, sold the p-System to Pecan,
Inc who went bust many years ago. A UK company, Cabot, then got a
license from UCSD. I understand that they had to get the manuals
typed back in from the paper. Cabot moved around and I have not had
any contact with them for over 5 years.


You might like to check out www.threedee.com/terak (Terak was a
machine that sparked off a lot of early interest in the p-System)


I also heard that a chap called Lucien Murray-Pitts
<lucien@tardis.ed.ac.uk> was OCRing the docs. I have never spoken to
him.
