   Uhh...VAXen don't talk to Sun keyboards.  If you're lucky, you didn't 
smoke the system or the keyboard.

   It's called the "keyboard port".  It's a four-pin modular connector 
that looks like a phone jack.  The correct keyboard for that system 
would be a DEC LK-201, LK-401, and possibly a few others.  Don't bother 
with other-than-DEC keyboards...I've never heard of a 3rd-party company 
making one that was compatible with these systems.

   Those correct keyboards, while proprietary (hey, what isn't?), are 
quite common in the DEC world.  Many different systems and terminals 
use them, and they show up everywhere, even on eBay.  A keyboard from a 
VT-220, -320 -330, -340, or -420 will work, for example.
