MicroVAX 2000 with Network Interfaces problems.

[Mattis Lind]

I have a MicroVAX 2000 that has suffered from a leaking battery. It has
been cleaned and seems to be mostly working except for the network
interface.

The startup reports

?? NI       0011.700E  V1.1


for the network interface.


The switch is set for thin ethernet, and a 50 ohm T is in the connector
with two terminators.


What does the failure code mean? I cannot find any document identifying
different failure codes. It seems that the software finds the version so at
least something is working.


Anyone that has an idea what is wrong?


I will try to examine the content of registers at 200E0000 and 200E0004 and
also if the ROM is accessible properly at 20100000 - 2011FFFF. But other
than that, what can be done?
