True. I'm just worried that the KA410 board won't survive the desoldering
experience (and the 5380 might not, either!). Some DEC boards do not like
to give up their parts.

I think it depends. The mouse and keyboard part are compatible, but I think
DEC had a couple of standards for how to get those signals from the external
peripheral connector into the CPU. You might need a VAXstation II GPX
cable to which you can attach an LK201-ish keyboard (not PS/2) and a DEC
puck mouse (+12V, not +5V supply).

The difference is a jumper - enable the onboard
frame buffer and look for
a keyboard/mouse or ignore the frame buffer and expect there to be a level
converter on the keyboard/mouse port and provide 4 TTYs.
I don't suppose one could use the monitor/keyboard/mouse cable of a
VAXstation II GPX? Also, is there any chance that the Ethernet is
disabled? I read somethiung to
that effect but don't know how to tell. At least it's got a small chip which
claims to contain the MAC address.
Ethernet requires a daughter card with the LANCE chip on it. The connector
is built in to the main board, but not the actual ethernet interface. Most
of the VS2000s I've seen had Ethernet, most of the uVAX2000s did not. No
real rule, except how much stuff cost and what the typical DEC customer was
going to use something for.
I'll trade
you a 5380 chip for the uVAX board! No desoldering required!
If only we weren't on separate continents. =) Since it's really my friends,
he'll take some coercing.
