This is a Heavily modded Atari 2600 Heavy Sixer. It is modded with the Longhorn Engineer V2.2E S-Video mod and the MIDI2600 mod. The Video mod enables it to output both S-Video and Composite Video as well as splitting the Audio Signal into two distinct Left and Right channels. The MIDI2600 mod allows the user to plug in a MIDI keyboard to control the Atari 2600. These coupled with the Synthcart create a fairly unique 8-Bit "musical" device.
