Thats the exact same error that was reported on the mtec card with the battery problem. Try the battery some more. I am 99% certain this is the cause of the woes.
So trying the 1230 on the working motherboard (batterly done as you said)
RED SCREEN:
Manufacturer 2192 product 32 status: defective.
Clicking continue gurued it and reset to the kickstart screen, before I could copy it down.
Now i'm at the workbench with 0 other mem... show config still gives 68030/68882fpu/68030mmu...
?
