Interesting question :-D

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 like way outdated, floppy OS's from way back in the day.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.

phys

PHYS(2) 							System Calls Manual							   PHYS(2)

NAME

       phys - allow a process to access physical addresses (2BSD)

SYNOPSIS

       phys(segreg, size, physaddr)
       unsigned int segreg, size, physaddr;

DESCRIPTION

       The  argument  segreg specifies a process virtual (data-space) address range of 8K bytes starting at virtual address segregx8K bytes.  This
       address range is mapped into physical address physaddrx64 bytes.  Only the first sizex64 bytes of this mapping is addressable.  If size	is
       zero, any previous mapping of this virtual address range is nullified.  For example, the call

	    phys(7, 1, 0177775);

       will  map  virtual  addresses  0160000-0160077  into physical addresses 017777500-017777577.  In particular, virtual address 0160060 is the
       PDP-11 console located at physical address 017777560.

       This call may only be executed by the super-user.

ERRORS

       [EPERM]	      The process's effective user ID is not the super-user.

       [EINVAL]       Segreg is less than 0 or greater than 7.

       [EINVAL]       Size is less than 0 or greater than 128.

SEE ALSO

       PDP-11 segmentation hardware

BUGS

       On systems with ENABLE/34(tm) memory mapping boards, phys cannot be used to map in the I/O page.

       This system call is very dangerous.  It is not considered a permanent part of the system.

       Phys is unique to the PDP-11 and 2BSD; its use is discouraged.
