Today I picked up a VT220 terminal from the MIT Equipment Exchange.
  It didn't have a keyboard attached to it, although a couple of 
  appropriate looking keyboards (Model LK201) were sitting nearby.

With or without a keyboard attached, the "VT220 Keyboard Error 4" came
  up on power up.  When the keyboard was hooked up, all for LED's were
  illuminated.

Incidentally, there was another VT220 sitting next to the one I took which
  had the same problem.

(I would try known-to-be-working keyboard/terminal combinations, but I 
  can't find any VT220's in the immediate vicinity.)

So, my questions are:  what is Error 4, and is this a problem inside the 
  VT220 or inside the keyboard?


Thanks for any suggestions,
