Check the BIOS Eproms for correct seat in the sockets and content.
It took me the whole damn winter to get back to you but you were correct in that something was wrong with my last burn and both the High and Low EPROMs did not have a valid image on them.
I've reburned Version 1.43 from the images here and verified they are burned this time.
No change in the POST codes, or signs of life, unfortunately.
