first off, i LOVE unix to death, but i really only like the text/console side of it. im not big into the XFree86/Xwindows side of things.. so with that known... im in search of really old *nix's.. like way outdated, floppy OS's from way back in the day. im kinda in search of the pure'r UNIX's.
if anyone knows where i could attain any of the following in open-source of course, i dont wanna pay for any of these, nor should i have to.. except maybe the last one... but that would be great to find these older OS's for study and testing..

The wishList:

4.2BSD, 4.3BSD, 4.4BSD
SVR2, SVR3, SVR4, SVR4.2
XPG3
ULTRIX-11
PDP-7, PDP11/20
Authentic V3,V5,V6,V7 (mainly 6 and 7)
Old IRIX
if possible BSD1.x
UnixWare 2.0
OpenServer 5.0

and i dont even know if it really exists, but an open-source AIX (older obviously).

if anyone could tell me where some of those are, id be very greatful.
