THE ACTION CHAIR The action chair is a rare item. Connected to a Genesis/Megadrive, it acts as a controller! When you lean backward/forward it tells the Genesis to go down/up and when you lean left/right it tells to go left/right. Two handles on each side offer two buttons each, resulting in 4 buttons : START, SELECT, A & B. The Action Chair is basically a chair mounted on a controller. It is thus possible to play all games with it, though it is more convenient to play games like After Burner II, Space Harrier II, Super Thunder Blade, Hang on, Road Rash, Super Monaco GP, etc. Thanks to **Spycal** for this picture /media/museum/hardware/sega_action-chair.jpg

3 BUTTONS JOYSTICK The joystick port uses a multiplexing technique based on the 74HC157 chip (high-speed cmos quad 2-line to 1-line multiplexer) built-in the controller. There are 2 inputs for each 4 outputs of the chip. The console can determine which function is read by setting the *select* signal to 0v (logic low) or +5v (logic high). **Fun fact :** Atari 2600 joysticks could be used in the Genesis joystick ports. The button of the Atari joystick was the "B" button on a Sega Genesis, and the direction buttons are fully functional. /media/museum/connectors/genesis_joystick.gif

The Wondermega was released in 1992 as a joint development by Sega and JVC. It is similar to the Multi-Mega, being a combination of a Mega Drive and Mega CD, but with the added ability to function as a karaoke machine and improved sound thanks to JVC's new DSP. The system shipped with four karaoke programs and a compilation CD of four games. Two microphones can be connected to the system so users can sing along with CDs, or, thanks to a button on the machine, the CDs vocals can be muted allowing you to sing with just the music as a backing track.

In 1993 the WonderMIDI package was released. This allowed users to connect a MIDI keyboard the Wondermega to create sound effects and music, and included instructional software which could help people learn to play the piano. 1993 also saw a re-release of the system, with several small changes designed to reduce cost.
