Aha - yep. Explains the large amount of Mach source that I found on the
same tape in that case :-)

Definitely French whoever they are/were, hence the "Systemes".

I'm trying to trace copyright ownership on all of this stuff at the
moment to see if I can make it all available. There's some source to
various Acorn things, including some partnership / relationship with
Chorus, and the stillborn ARX OS - plus documents that show Acorn's
thinking on CPU and OS direction in the early 90's. I love finding stuff
like this, but I suspect that I'm not going to be allowed to share it   
:-(
