Yes, that was one of the RTS compilers for the NU machine. John Romkey may
have done it, as he was the primary person behind PCIP, but I can not claim
I remember who did the 8086 backend. IIRC Jack Test did the 68K backend.
The RTS crew had the NU machine and NU bus that went with it. Very tean
project Neat project. Similar idea, in fact to what CMU was doing with the
Intel Mutlibus called the distributed front end (we had started with LSI-11
and cost reduced it to 8086 on a Intel Multibus). Andy Bechtolsheim would
take with him to Stanford and rework with a 68K which became the
Stanford Network Terminal - which used the RTS's C compilers. It's all
very mixed up. [ Don't tell me there was not an open source culture back in
the old days by the way].
Anyway the MIT RTS foilks made hardware and PCC back ends for the 68K,
Z8000 and 8086. I believe that each had separate assemblers, tjt who
sometimes reads this list might know more, as he wrote the 68K assembler.
IIRC they had a common linker which is was rewrite/extension to the
original V7 linker or maybe the 4.1 linker.
Anyone with a V7 license could get it. If you had a PC license you get
get the source to Romkey's PCIP. If you did not a license, you could only
get a binary kit.

the licensing material for this product, IIRC, included some kind of

been lawyering to CYA rather than including anything).
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.
