I just donated my extra copy of Xinu tapes and floppies to the computer museum
(along with first editions of the books).

I'd be happy to join.

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.

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.

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.)

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,

Franklin Ace? I had one of those. Probably still do, somewhere.

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.

Well, I usually assume an Apple ][ at least has THAT ability (as any with 
at least 64K will) :P, but the NMI issue would be the problem. :/
