  The PC/IP software from MIT included a port of the
"Portable C
 Compiler" to generate 8086-era code. It ran on a Unix machine and built
 binaries that you downloaded to the PC. ... So you need an ATT source
 license to get the full PCIP dev kit. 
That makes sense. The 'MIT license' (about which Jerry Saltzer did a note for
the October-December 2020 issue of the 'IEEE Annals of the History of
Computing', available here:
  https://www.mit.edu/~Saltzer/publications/MITLicense.pdf
and which mentions that it was initially done for the MIT PC/IP code) only
applied to the MIT-written applications, not a 'derived work' (to use the
intellectual property law 'term of art') based on Bell code.
