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

Hello, Warren, Excuse me for my abruptness. I am
QingFeng Hao from
China and got your mail from the website through google searching, :-).
I know you're expect on the operating system. Now I am researching the
Unix V6's source code , but I met some questions, if you could spend
some time to give some aim, I 'll apprecite it much.
Question1: After startup, process 1 runs in the user mode and execute
the file /etc/init actually, right? So what's the /etc/init's content?
When was it written to the disk(combined with Unix)?
Question2: Do you have any documents about the peripherals such as
KL-11, PC-11? I just got a pdp11/40 and a simple hardware manual from
the website. But they are not enough.
Thanks a lot.

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
