We dealt with the 286 when I was at Mark Williams. They had done the compiler that Intel was using and reselling at the time. When the 286 came out, they were concerned about performance, what with the goofy segment registers and all the various memory models (compact, small, medium, large). The wanted us to guarantee that the performance of the compiled code would be equal to or better than the 8086. Naturally we resisted.
So you must know Ron Lachman.
Oh, also at Mark Williams, the year before I started with them they demonstrated Coherent (v7 unix-alike) on a vanilla IBM PC without any memory protection hardware. Later also done on the Atari ST.
