Should act as voltage divider\nfrom 0v to 7v, only have 5v so\nhere's to hoping it'll be enough!

Hopefully a functional part of the display section used in the Atari 2600 console. This is\nNTSC for the time being as the PAL circuit is somewhat more complex with regards to\ntiming. Color delay is limited by the 5v supply, hopefully this will be sufficient.
