I'm much more interested in reconstructing a running system, myself.
The documentation is great to have, but its already readable (although
not searchable) in the current pdf. At least in most places (there
are
some really faded sections).
I think it's fascinating that we may end up with a working first
edition Unix which has been *typed in by hand in 2008*. None of the
bits will actually be the original ones. Borges would be proud
("Pierre Menard, Author of the Quixote" is the story I am thinking of).
If anyone is looking for volunteers I would have a go at typing bits
in, but I do not know how much time I'm likely to have.
