I just like to agree with Andrzej that some of the applications and
libraries in Minix would be suitable for producing a small FreeBSD.

I'd also like to suggest 2.11BSD, which at present has most of the
functionality of 4.4BSD-Lite, but runs on the 16-bit PDP-11 platform.
Some of 2.11BSD is contaminated with AT&T UNIX code (mostly the kernel),
but much comes from 4.4BSD-Lite. So the source code from this system
might also be useful.

The only problem is how to get it. First you need to get a UNIX source
license. Easy. Read http://minnie.cs.adfa.edu.au/TUHS/archive_access.html
for details. Then go to

http://minnie.cs.adfa.edu.au/TUHS/Archive/PDP-11/Distributions/ucb/2.11BSD

to retrieve the full source code. You can also find an exploded tree of
2.11BSD source code at

http://minnie.cs.adfa.edu.au/TUHS/Archive/PDP-11/Trees/2.11BSD/

I just checked, but the Bourne shell in the 2.11BSD code tree is the _real_
one written by Steve Bourne.

Cheers,
	Warren
