Subject: 2.11BSD
I don't know what got into me. I decided to fire up a PDP-11. I have not
touched one of these for about 5 years. I've mostly been messing with
embedded Linux stuff.
The 2.11BSD patch archive has gone offline. Do you know if there is a
mirror of this somewhere?

Hi, Quing Feng,
at http://www.ba-stuttgart.de/~helbig/os/v6/pdp11 you'll find a detailed
description of the pdp-11 and its peripherals as needed for understanding design
and implementation of V6.
and at http://www.ba-stuttgart.de/~helbig/os/script/chapt2.4 you'll find a
description of the init process.
have fun,
Wolfgang Helbig

Hi QingFeng, I think you should join the PUPS mailing list ( see
http://minnie.tuhs.org/mailman/listinfo/pups ), as the people on
the list should be able to answer your questions.
Q1: The source code for V6 init.c is here:
http://minnie.tuhs.org/UnixTree/V6/usr/source/s1/init.c.html
Q2: I would browse through this area of bitsavers.org:
http://www.bitsavers.org/pdf/dec/pdp11/
Hope this helps, and if you have other questions please e-mail them
to the PUPS mailing list, so that we can all help you out.
Cheers,
Warren
