Hmmm. Line 530 of esp.c in the linux-mips-2.0.21 kernel says

case esp100:
        return "Sparc ESP100 (NCR53C90)";

That looks like a start. I wonder if the chip in the Magnum 4000 is the 53C90 
another rev. I looked in my 4000 SC and it's got a Western Digital chip.

Ryan, please relay this message to
