Commodore 64s, ZX Spectrums, BBC Micros and the like never came with monitors, you just used your TV. This board has HDMI out on it, or composite if you solder in a connector, so you can use it with your existing TV or monitor. A mouse is optional too, you can do everything you need to from the keyboard. So really, it's only a keyboard that you need.
