Have Xinu
media to go with it? It's something I've been trying to track down. ;)
Have you asked Doug? I've copied him (Hey Doug, you should be on this list, all the long
time unix nerds seem to be
here, lots of fun with memory lane).
I'd be happy to join.

I should mention that I "ported" Xinu over to the Apple ] [ when I was at
uni: I transliterated the C code into assembly and used an external 555 timer to generate
the clock ticks. Fun times!

I loved Xinu, it was sort of like the legal Lions book with source code.
And Comer's coding style is pretty similar to mine, simple obvious stuff
for 99% of the code, you only got clever when it was actually important.

It's available at ftp://minnie.tuhs.org/pub/apple2/apple2xinu.tar.gz with
source code, binaries, floopy images and some documentation.
No, it won't run on a real Apple ][ without some work. I actually wrote
it for an Apple clone which had bank-switched RAM and I made use of that
to hide the BASIC ROM and store the OS in the upper 12K. You would also
need to simulate a 10 or 20Hz NMI as well :-)
Cheers,

I ported Xinu to a Motorola 68000 on VME card. I had the luxury of a
working C compiler, so there was very little assembly language required
(context switch only, from memory). The main effort was in rewriting device
drivers for the relevant hardware. The result was used for teaching
Operating Systems.
Unfortunately, I no longer have the code.

nice! i have the lsi-11 editions (1984) of the xinu approach on my shelf,
up through the linksys edition (2012). i've spent a small fortune on his
books, second only to tanenbaum, i would think. (not a terribly big
stallings fan, but he's certainly prolific.)

Ahh! I wonder if they'll be making images and PDFs available?
It seems like a place that'll help with my crazy projects, too.
