No, thank you! This is something I didn't even know existed, and now I'm very curious to find out more. Although chances are slim, maybe that software turns up somewhere someday (it would be brilliant if it's on one of the machines I got, since except for the one that was my own in the 80s, I did not get to even see them yet--shipping them over the ocean would not just have been expensive, but risky, too).


I've published a few screenshots at the Retrocomputing Forum, https://retrocomputingforum.com/t/a-bit-of-xenix-history/186...


If it’s there, please preserve and document it. There’s very little left of it anywhere else.


Of course. I found some other stuff in the 1.2 kernel by the way, like the existence of (relatively smart, apparently) network and serial multiplexer cards for the PC-X.

I also reverse engineered how the NMI worked, details about the MMU etc.
