BTC Clickerty Clack computer keyboard.
This is an old computer keyboard from the 90s. There are people, like me, who prefer not only the sound but the sensation/feel of using an old-styled click clack keyboard. Typing feels more direct with one of these than the low profile versions around these days. You would need to check if there are adapters to suit the connectors. I show an adapter at left in the last photo, required to connect to my PC computer. Yours might be different.
