Ok, Serguei. The pictures help.

Connectors on the monitor itself is not that relevant. The output from 
the workstation will be just three coaxes, with sync-on-green. The 
monitor itself is a generic device, that can also use separate syncs 
(hence the connectors), but DEC didn't use those.

That was an odd mouse. Interesting. I actually did use a VS I many years 
ago, while at DEC. But I've long since forgotten any physical details.

Yes, this was the most useful picture.

DEQNA is the ethernet controller. It has a DA-15 AUI connector. Bog 
standard thing.

The "keyboard" connector is another DA-15. It is the same connector for 
both keyboard *and* monitor. You'll have to find a matching cable. That 
cable will have a DA-15 at one end, and a block at the other end, from 
which there comes three coax cables for the monitor, and you'll have a 
4-pin modular jack, into which you plug your LK201 keyboard. It might 
also have a connection for a more standard DEC mouse, which have a round 
DIN-connector with 7 pins or so.
