DECstation 3100 self-test failure

Hi,

I've aquired a 3100 that I'm hoping to install NetBSD on. Unfortunately
it fails the self-test:

KN01 V7.01

7..6..5..4..3..2..
??

From what I can gather from the 'net, test 2 is the LANCE Ethernet
controller. I've tried both an AUI transceiver and BNC terminator but
still get the failure. Is there any hope or have I got a dead board?

If it helps, when I hit the reset button I can get to the prompt but
when I try and run any of the tests, eg. 'test -c', it just hangs until
I either enter ctrl-C or press the reset button.

Thanks,
George
