I like to comb second-hand stores for overlooked geek books, and came
across Interactive Programming Environments, which includes a copy of
Kernighan and Mashey's UNIX Programming Environment paper from '81. 
There's an interesting passage:

"UNIX has spawned a host of offshoots---at least six companies offer
or plan to offer systems derived from or compatible with the UNIX
system...."

With a footnote listing the companies:

"Cromemco, Onyx, Yourdon, Whitesmiths, Amdahl, and Wollongong Group."

Does anyone know what became of these companies and the products they
did (or didn't) produce?
