I'd guess that the human-readable model is probably XP221, though that
doesn't lead to a lot via Google. However you might find a usable PSU
under eBay #271338697806. Ouch, $80 + S&H.

Tek made some very nice X terminals, I worked with them in the '91-'94

Announcement of the XP200 line is here:
(Too early to cover that model, though.)

There's a Linux how-to for supporting/booting Tek X terminals that
includes the pinouts for the power connection. Good luck with the 16
year old links for software, however...

Good luck,
