The only non American one I was aware of came from Brazil, TROPIX.

I’d written a small thing about it here

I’ve seen mention of something out of Sweden, although nothing concrete on the name.

There is also Демос/DEMOS the BSD code that had been stolen during the cold war, and ported to various Soviet machines & localized.

Does anyone have documentation or history for European efforts in the Unix-like operating systems? For example there was Bull’s Chorus which I seem to recall was based on Mach or a competing microkernel (it was a very long time ago and I used it for no mare than about two hours..).

I am rather saddened by the fact that there is so much about all the Unix (and not only Unix) history of computing in the USA and so very little in Europe. I wouldn’t even know where to start, to be honest, all I have as a history is the Italian side from my father and his other mad friends and colleagues in Milan. So little of it is recorded, never mind written down.
