I have a Tektronix VT220 compatible keyboard as
pictured here:

Can anyone provide any information/links/technical specs?
Check this PDF for mention of a terminal that offers a VT220 style
keyboard:

Start with terminals that offer a VT220 personality:

I suspect it
is off either a character terminal or an X-terminal. If I can't find
anything about the protocol the plan will be to replace the controller,
Protocol would be described in the service manual for an earlier
terminal, but I've never seen a service manual for any of the X
terminals. (Not even one for any brand of X terminal, not just the
Tektronix ones! I'm sure they exist, but I haven't seen one.)
