I was pointed to the book “Writing Solid Code”, Microsoft Press ISBN 1-55615-551-4. In the foreword it says:
"The system we used to develop Multiplan was pretty sophisticated for PC development in those days. We wrote the core product in C - most programs then were written in assembly or Pascal. We did our editing and compilation on a PDP-11 running Unix. The C code was compiled into p-code and downloaded to the target machines. We had to build p-code interpreters for each microprocessor in use at that time. By the end of 1983, we had interpreters working for the 8080/Z80, the 6502, the Z8000, the 68000, the 9900, and the 8086.”
So the Simonyi compiler was Xenix/Unix native.
The specs for its p-code interpreter can be found here:
