Does Novell have any supported Operating Systems that will work on devices with the below specifications?
If not, does anyone have any suggestions?
CPU1:
CPU2:
CPU=“Celeron (Coppermine)”
Clock: 566 MHz
Cache: 128 kb
Memory Size: 256 MB
20 GB HD
Thank you
System requirements for SLED are at
https://www.suse.com/products/desktop/technical-information/
and are above the specs you cite but depending on exactly what those CPUs are (got model numbers?) if you can scavenge some more RAM you may be able to run SLED. You might be able to run SLED on the 512MB one, I’ve run it with 768MB RAM in a virtual machine.
You could try the Network installer of openSUSE and install a lightweight desktop environment such as xfce

Take a look at
https://forums.opensuse.org/showthread.php/492469-openSUSE-13-1-with-500-MB-RAM
And

These distros are all about low resource usage

What’s best depends in part on exactly do you want to do with the machines you cite.
You may wish to consider asking in a more generic Linux forum such as
http://www.linuxquestions.org
You’ll probably get at least as many different suggests as you do replies 
FWIW SLED 11 SP3 64bit boots on a Virtual Machine with 512mb RAM and limited to 40% of one core of an Intel(R) Core™2 Quad CPU Q9550 @ 2.83GHz. It would probably be reasonbly usable it you didn’t run more than one application at a time and didn’t ask it to do too much. But even with the CPU limitation it’s probably got more CPU power than the machines you cite. And of course installing hardware below SUSE’s stated minimum spec would probably be an issue if you ever wanted to get support.
Thank you very much!
I wanted to ask a few questions before pounding my head.
