This I didn't know.
I bought a Tektronix 4207 color graphics terminal without a keyboard
recently. Finding the correct keyboard part number seemed to be a
process with great uncertainty, the VintageTEK folks said the correct
one was a 2468. One of these was for sale on ebay for $300 - no way was
I paying that much!
So I tried one that looked like the keyboard in the TEK catalog of that
period, but with a different part number. The connector looked like the
right one though. I got one off ebay, and I thought it was kind of
expensive, but it did work with the 4207 terminal.
What I didn't understand was a fascination with the black mechanical
Cherry switches the keyboard used. These turn out to be extremely
popular with the 'gaming' community. I don't know if the tektronix
keyboard can be used with a modern PC, I haven't looked at the interface
signals yet. The modern PS/2 keyboard has a clock and data line, the
DEC LK201 used rs232, so what Tektronix used is anybody's guess.
