It was thus said that the Great Eric Smith via cctalk once stated:
The Intel iAPX 432 was also designed to explicitly support block-structured
languages. The main language Intel pushed was Ada, but there was no
technical reason it couldn't have supported Algol, Pascal, Modula, Euclid,
Mesa, etc. just as well. (Or just as poorly, depending on your point of
view.)
The iAPX 432 could not have supported standard C, though, except in the
sense that since the 432 GDP was Turing-complete, code running on it could
provide an emulated environment suitable for standard C.
What about C made it difficult for the 432 to run?
-spc (Curious here, as some aspects of the 432 made their way to the 286
and we all know what happened to that architecture ... )
