Bring back a legendary vintage television from the space age!

This guide walks through how convert a classic RF CRT TV into a monitor for Raspberry Pi or any desktop computer.

With a couple cables and a signal boosting box, you can output the signal from just about any computer to the JVC Videosphere.
