Unfortunately the 3/60 does not have the extended diagnostics of the
3/50, which are very useful for finding problems. The extra ROM space
was used for more boot media options.

Unless there is further damage to the board, try rejumping J800 and
connecting an external AUI transceiver. If the internal transceiver
module has gone open circuit then this should restore the correct
loads on the ethernet chip.

Given that you have managed to get as far as ifconfig, I assume you
have a disk connected, so if you don't want networking you could just
comment out that line and use it standalone.

The ethernet address on 3/60 is stored in the IDPROM, so that's no
indication that the ethernet hardware is OK.
