Hi,
I'm a programmer and I want to learn more about UNIX.  Does anybody
have a link to somewhere I can find the source code for an early UNIX
system so that I can start exploring the code?

thanks in advance for your help.

This is the famous "Lions book" that include not only the source code
to 6th edition Unix, but also a lot of useful commentary on what the
code actually does.

Why focus on old system why not look at some thing current like the
OpenSolaris code

Maybe he is interested in some historical aspect.  Maybe the current
opensolaris code is just too much to digest at once.

Newer systems are bigger, and has a lot of recently added features.
It is hard to distinguish which functionality is one, which makes Unix
Unix, and which is bells and whistles added by particular vendor.

There is also special system, designed to serve as learning material.
It is called Minix. Recently version 3.0 was released.

A lot of the opensolaris code is probably old - not changed for several year
s
(so it would be interesting from a historical viewpoint), but it's not possi
ble
to tell since there's no history.

He's better off reading the CVS for FreeBSD, if he wants to learn something.

What "makes Unix Unix" is largely a matter of opinion, and to some
degree religion.

Or Plan 9, which is what the original fathers of unix wanted unix to
be.
