I wonder why the unchallenged existence of Unix clones like COHERENT and Minix wasn't enough to kill the trade secret argument before it even got out of the gate.
It was a V7 clone (like Minix).  I've forgotten but I thought it originally ran on 286 (again like Minix).

I'm not sure why it was not as popular.  Maybe the difference was that it was a V7 clone and closed source as it were

Clem, is your paper online somewhere?
​Not yet - I'll send out an URL when the conference papers all go on line, but if you privately send me a message I'll send you a PDF.  Note, a couple of you have an earlier (near final) draft, so send me a note if you want the printed one.   The differences are minor-> some clarification/some small rewording to dealing with English colloquialisms that were not understood by the French. ​
