Are there any sources for used/refurbished motherboards for an Althin system 1000 other than Baxter?

I have a source. Just email me and I can get you the info. svrdcct@cs.com

Any of the pre 586 rack mount mother board machines, use generic intel mother boards. You can use any generation, that you can find, provided you replace the BIOS with the Althin machine BIOS chip. We've actually ordered 486 MB's off of E-bay and used them in our machines.
