I think this is does a major disservice to Thompson's work. I'm not that
familiar with the ETH compiler, but Turbo Pascal is a horrible example. Not
only was it for a single architecture, but it let that architecture show
through to the user level. It didn't even implement a full Pascal... it was
a subset (no standard Pascal I/O, for example) with extensions. The Thompson
compiler is extremely hardware-independent and generates good 68020, MIPS,
and Crisp code. It also implements full ANSI standard C, not a subset.
Oh yes, not only was the compiler 8086 dependent, it was also restricted
to small model on the 8086. Programs larger than 64K had to use overlays.

Isn't that ground-breaking itself? Particularly in contrast to things like
OS/2... let alone the gross disasters that MS-DOS and the Mac system software
have grown into?
