- title: THE ACTION CHAIR
subtitle: ''
text: |-
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.

- title: 3 BUTTONS JOYSTICK
subtitle: ''
text: |-
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.

The Mega Drive launched in 1988 in Japan. Europe had to wait two whole years before they would get the machine.
Designed as the replacement for the 8 bit [Master System](/museum/sega-master-system/), it originally competed against other 8 bit systems, namely the [Famicom/NES](/museum/nintendo-nes/) and [PC Engine](/museum/nec-pc-engine/)/[TurboGrafx](/museum/nec-turbografx-16-turbografx/).
The Mega Drive had mixed fortunes. In Japan the console was out sold by both the PC Engine and later the [Super Famicom](/museum/nintendo-super-nintendo-entertainment-system/). In Europe on the other hand, the Mega Drive fared considerably better. The practically unheard of TurboGrafx was extremely rare and the Mega Drive was able to outsell the [SNES](/museum/nintendo-super-nintendo-entertainment-system/), finishing the generation in first place.
However, the success of the console in Europe, and as the [Genesis](/museum/sega-genesis/) in the States, may well have contributed to Sega's downfall. Two misjudged add-ons, the 32X and Mega CD put a huge dent in Sega's reputation, one so large that the company would never recover.
A redesigned [Mega Drive II](/museum/sega-mega-drive-ii/) was released in 1993. The smaller console was cheaper to produce, similar in concept to the [Master System II](/museum/sega-master-system-ii/).
