I remember the “technical Computer center” people at Chrysler where I worked talking about making the PL/M compiler run on our CDC Cyber computers (60-bit). It was a bit of work. I seem to remember thinking it was written to run on an IBM mainframe, if that makes sense. But they got it working and we used it until Intel came out with their 8080-based development systems. Then we started using them to compile.
