Yes, I spent a good amount of my time at CMU in the late 70's re-
writing the TOPS-10 version of that compiler with a new P-Code
definition so that the target code could be run efficiently on small
machines. I did the original work to target the PDP-11s on C.MMP.
I still have the compiler source, documentation I wrote and all of the
test cases. Unfortunately I no longer have the PDP11 P-Code
interpreter that I wrote (all in PDP-11 assembler and BLISS-11). :-(
However, I *think* I still have the interpreter I wrote in Pascal that
I used for testing the compiler changes and code generation.
