Buying old keyboard or old computer / terminal keyboards

Looking to buy old computer and terminal keyboards

The keyboards that I'm looking for don't have USB cords on them and defintely aren't wireless.
They have round connectors and other odd connectors.
If you have the terminal or computer that it went with, I may be interested in that as well.

Please send a clear picture and an idea of what you want for them.
If it was made before the mid 1990's and makes a very clicky sound when you press a key, that's what I'm looking for!
It may have been a beige color and became a yellowish color.

Thanks!
