Success!

I found that if I set the "break enable" switch to the up position,
the console moved to port 3 and I could then see all the NetBSD
startup messages. Once I could see what my network device was, I
could configure the network, mount my root and swap and then
everything worked.

The boot messages are included below for anyone who is interested.

Many thanks to all those who replied.
