Yes. Ken wrote the first version for the National 32000 (maybe even 16000?)
on the Sequent. He ported to the MIPS when we started Plan 9.

What is the history of Plan9's C compiler? Was it
a from scratch
implementation?

Chris Fraser and Dave Hanson did LLC and wrote a book about it, very clean

I believe Snyder was an MIT Master's thesis,
finished in 1975[1]. There
was a fair amount of C and compiler work at MIT LCS, perhaps JNC can post
some info. I think Snyder's compiler was used for the MIT PC/IP[2] project;
the links at BitSavers imply they are related. PC/IP brought TCP and
clients to DOS 3 machines and was commercialized as FTP software and was
one of the reasons for the creation of the MIT license[4]. BDS C[3] was
done by an MIT drop-out, Leor Zolman. I bought my first motorcycle from him
:) BDS C was used for the first implementations of MINCE (mince is not
complete emacs -- those kinds of acronyms were popular) and Scribble,
downsized clones of emacs and Scribe, respectively.

Judging from what's at the bitsavers I posted, the source for pcip and
this is the backstory to them.
