I found a couple postings regarding the NS1000 a number of weeks
ago when I was looking for more information. I tried to find
some downloadable archives of this list to avoid faq-type questions,
but I have not found anything for off-line reading yet.
I wrote the original patches for linux on the NS1000, so here is
some background on where I am at.

I pretty much reverse engineered the boot process using a JTAG debugger
and watchpoints on data areas, etc. Most of what I know is in the source
code patches. The single biggest problem for me has been trying to locate
some documentation on the IBM27-82376 ISA bridge. I found some snippets
in a reference design .ps for the 82660 host bridge, and that is it. So
anybody with any information on it, please email!

I use an NFS mount here by now, I don't remember what shape the initrd
root fs was in.

I added a really shaky patch for true color support on the Trio chip
in the box. It works with the 4.1.something fbdev X server up to
1024x768 at 16bpp. Sound and pcmcia works now as well. The latest patch
for linux 2.4.19 is here:
I can't sem to find the message in question, but I read somewhere else
that the GPL in the ncdcs tool is a problem for inclusion in BSD-licensed
sets. I GPL'd the linux version since I would like that to become part
of the mainline code at some point. If someone can point me to a
recommended BSD boilerplate and instructions for submissions etc then I
can produce a BSD-licensed version as well.
Also, if anybody has archives for the ppc-related netbsd lists other
than http://mail-index.netbsd.org, please let me know if there is a way
to obtain a copy.
