The Commodore is a home computer from the 1980s.

The +4 has a number of interfaces which can be used to connect to the outside world. These include a serial UART, 8-bit parallel port, cassette port and a CBM IEC serial bus.

Video output includes composite video which can feed, for example, a Hauppauge HVR900H capture board in Linux (as shown in the photo). In Linux this setup has low latency and is very usable, this may not be the case elsewhere.
