[TUHS] Xinu in emulation, e.g. SIMH?

[Chris Hanson]

Has anyone gotten Xinu running in SIMH? It seems like it should be straightforward to run the "support" utilities under BSD on an emulated VAX and then run Xinu itself on an emulated LSI-11. If anyone's done so, I'd be interested to learn what all you had to do to set it up and get it working.

Is this Doug Comer's XINU?  I haven't talked to him for a while but he
was one of my heros like the Bell Labs guys.  I loved his code, it
was so simple like the Lions doc for v6.

I can try and drag him to be here, that would be cool.

Yeah, Comer’s XINU book at Tannenbaum’s MINIX book are the books from which I learned C, so now that I have an LSI-11 I’d like to get the former running. (I ran MacMinix in the early 1990s, and even published a patch to flush the 68040 caches on context switch so you could leave them enabled…)

Yes please. I learned C from the Xinu book when I translated Xinu into 6502
assembly to get it to run on an Apple ][+.
