I read it as if the UCSD p-system was an OS, but I do not
see that it was written in USCD Pascal.

JVM is a VM that runs Java code, but it is written mostly
in C++ AFAIK.

USCD p-system could be similar.

PS: There has also been experiments writing most of a JVM in
     Java like Maxine and Jikes RVM.
