"significantly lower level affair, on par of the other Star-something languages for the CM"

I'm not sure what this means. C* and CM Fortran weren't particularly low-level, unless C or Fortran 90 are "significantly low-level". For low-level fun, you'd drop to Paris (or to CMIS for "breathtakingly heart-stoppingly low-level").

For the curious, a great archive of documentation for stuff that actually shipped is here: https://people.csail.mit.edu/bradley/cm5docs/
