Source for Unix???

Umm, well, that's not *quite* what happened.

UNIX was sold to educational sites, in source form, for a low cost;
however, even then, it was considered trade secret code by AT&T, so
those sites weren't supposed to freely distribute UNIX source to *other*
sites unless those other sites also had AT&T source licenses.

I don't know that AT&T copyrighting the UNIX source affected that; AT&T
was also increasing the cost of educational source licenses over time,
but that was happening even before they copyrighted the source.  I
*think* educational source licenses may still be available at relatively
low cost, although the cost is higher than it was.

I'd be *extremely* surprised if JHU didn't have at least one UNIX source
license.  Try asking around a little more widely...

>I am really interested in reading it,

...and also be aware that, over time, UNIX has gotten bigger, so there's
more source to read; you may want to select which bits you actually want
to read.
