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

[Chris Hanson]

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…)
