Where can I find 'uname' outputs for the major Unix OS's?

I am writing a script and would like to be able to parse the output of the uname command (specifically the OS name, and OS version).  

For example, I know on a HP-UX 10.20 system, "uname -n" will respond with "HP-UX".

Where can I find the output for the following Unix operating systems:

AIX 4.3
AIX 5.2
Solaris 7,8,9
HP-UX 11i
Redhat Enterprise Server 2,3

I don't have access to these systems, otherwise I would run the command myself.

uname -s  will report SunOS
uname -r  will report the SunOS version number, ie: 5.7, 5.8 or 5.9

Redhat ES2,3

uname -s will report Linux
uname -r will report the Linux kernel version (this will vary depending on what kernel update you are running)
cat /etc/redhat-release will report the Redhat release details

Don't have access to the other flavours.

uname -s  reports AIX
echo `uname -r`"."`uname -v` reports release version (not shure for newer versions of AIX)

uname -s reports HP-UX
uname -r reports release version

uname -s reports IRIX
uname -r reports release version

uname -s reports FreeBSD
uname -r reports release version

uname -s reports scounix
uname -r reports release version

Thanks to everyone who replied.  I split the points based on the number of OS's given in your answers.
