This is provoking some vague memory...

I recall there being two possible transceiver boards in the PWS. I call
it this because I think the tulip chip is on the main i/o board, but
then there is a separate board holding the physical interface. One
model has just a 10baseT connector, and the other type also has coax
and AUI. I think the one which has 10baseT, coax and AUI doesn't
support auto-negotiation on the 10baseT port. The one which has only
10baseT does do auto-negotiate correctly.

There was the same situation with the DEC DE500 PCI cards. Some early
models didn't do auto-negotiation. I guess they were probably DE500-AA,
though I mainly remember them as having some orange component on the
board. Later DE500-BA (with no orange bits) did auto-negotiation just
fine.

I don't think the tulip was such a bad ethernet NIC - we never had any
real problems with them...
