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).
That's exactly the cable I intend. It's the D15->3?BNC cable with a wart in
the middle for connecting the LK201 and hockey puck.

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.
This card is totally bare, lacking any daughter boards. What a shame.

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.
My friend is experienced. I only wonder if the card will run without that
quasi-SCSI chip.
