Evolution of the Game Pad

HOME > Computers > Game Pad

I was looking at some classic game console joypads the other day, and I began wondering how their features developed over the years. So, here's a first draft of a history of the joypad, in roughly chronological order.

The TV Tennis Game Paddle

Binatone TV Master controller An analogue control based on the monostable and triggered by the frame sync pulse. This particular one with the snazzy orange plastic case is from the Binatone TV Master MK IV. Game-start buttons were often located on the console, not on the paddles. Some TV games didn't even put the paddles on wires, but placed them on the front of the game box itself. One particularly odd machine in this respect was the Videomaster Superscore, which not only mounted the controls on the front of the console, but it also used roller-style controls.

Commodore 3000H controller Another slightly strange option was the use of slider controls, such as those on the Commodore 3000H TV Game. One slider, labelled ‘Bat Control’ was located on the console itself, while the other slider was in a separate hand-held box. My example is a PAL version and is labelled in German as well as English.

Commodore 3000H controller Inside the Commodore slider paddle, there's simply a 1MΩ potentiometer, wired up as a variable resistor. Two additional sliders connected to a single 5-pin DIN plug for four-player games.

Atari paddle controller Generally, with the early TV tennis games, there were no buttons on the paddles. These paddles were made by Atari and have a side-mounted button as well as the usual rotary paddle control. Thanks to Maarten Foukhar for the photo.

The Atari 2600 Joystick

2600 Joystick A digital, four-way joystick with a single fire button. Introduced in October 1977 with the Atari Video Computer System (VCS), later renamed the Atari 2600. Set the standard in joysticks and interface connectors for many years. Again, game-start controls on the console itself. Need photos: Quick Shot joystick.

Switch Joystick Many manufacturers made Atari-compatible joysticks with four direction switches and a fire button. Here's an example in clear plastic, where the user can see the four high-quality microswitches at the bottom of the stick. Shame they didn't use a microswitch for the fire button, too.

The Atari 7800 Joystick

7800 Joystick The Atari 7800 controller is a digital, four-way joystick with two fire buttons. Simply adds an extra fire button to the 2600 joystick. The wiring is cleverly arranged to maintain compatibility with the older 2600 joystick, with just a couple of resistors forming a crude OR gate. My example is missing the screw-in stick, but still functions as a joypad. Buttons are labelled ‘1’ and ‘2’.

Oddity: The Foot-operated Joystick

QJ Footpedal A peculiar gadget, the QJ Footpedal System was designed to work with the Atari joysticks and other compatible machines. It has three foot-operated switches, as well as a set of configuration switches. You could set it up to operate a driving game, presumably. QJ model SV-129, patent pending.

The 8-bit Home Computer Joystick

Voltmace Joystick An analog joystick with a single fire button. Many UK gamers would remember the BBC Micro and its 15-pin analog port, which was usually used for a joystick. However, other machines had similar (but incompatible) ports, such as the Dragon 32. Games were generally started from the BASIC interpreter of the machine, using the keyboard. Need photos: Dragon joystick, Apple ][ paddle.

The Vectrex Joystick

Vectrex Joystick An analog joystick with four buttons. The Vectrex was an 8-bit, vector-scan console introduced in 1982. It had two controller ports, and each controller had an analog joystick (sprung to centre) and four buttons. The analog-to-digital converter (ADC) for the joystick was located in the console itself, not in the controller, and two wires carry the analog signals through the cable to the 9-pin plug. The function of the buttons was shown on the screen overlay. Games were started from the controller using the normal fire buttons. The four buttons are labelled ‘1’ to ‘4’.

The Nintendo Entertainment System Joypad

NES Joypad A digital joypad with two game-start buttons and two fire buttons. First used on the Nintendo Family Computer of 1983, and later sold around the world as the Nintendo Entertainment System (NES) from 1986. The NES joypad introduces the idea of placing active components and circuitry inside the joypad. Each joypad has an 8-bit CMOS shift register chip in it (the 4021) and the console contains hardware to communicate with it. This reduces the number of wires required in the cable from nine (one per button, plus ground) to just five. However, the NES has a seven-pin connector (the two extra pins were for the light gun). The shape of the game pad, however, is a very basic rectangular box. The two fire buttons are both red in colour and are labelled ‘A’ and ‘B’.

NES Advantage The NES Advantage was a much larger, arcade-style joystick for the NES console. It has a double cable and can be switched between acting as the ‘Player 1’ controls and the ‘Player 2’ controls. It also features variable speed auto-repeat on the fire buttons.

NES Zapper The light gun for the NES was officially called the NES Zapper. This example has the optional add-on gunsight, clipped on top.

The Sega Master System Joypad

The Sega Master System was a Z80-based console released in 1986, but I don't have one! Refer to the excellent Wikipedia article for more information.

The Super Nintendo Entertainment System Joypad

SNES Joypad A digital joypad with two game-start buttons and six fire buttons. The Super Nintendo Entertainment Sysytem joypad extends the 8-bit shift register of the NES to 16 bits, although only 12 bits were actually used. Exactly the same interface circuit will read a SNES pad as was used for the NES, simply clocking the shift register 12 times instead of eight. There's also a different connector on the SNES pad, but the same number of active wires in the cable: five. It also introduces the idea of shoulder buttons, and it is shaped much more naturally to fit the player's hands.

SNES Score Master Like the NES, an arcade-style joystick was available, called the Score Master. This joystick includes the two shoulder buttons of the original, but moves them into the same group as the main four fire buttons. The fire buttons retain their usual colour coding, while the two shoulder buttons are grey.

Acclaim Dual Turbo I also have an infra-red cordless controller called the Dual Turbo, make by Acclaim. The design of the IR receiver unit is quite clever; it plugs into the two controller ports on the front of the console. Because the two ports are arranged symmetrically, it can be plugged in either way round and still work properly! It takes four AAA batteries in each controller, although I don't know how long they last in use. This one has the fire buttons coloured in the US style, in two shades of purple.

Logic3 FreeWheel For driving games, I have a FreeWheel controller by Logic 3, which uses mercury switches to sense rotation and tilting of a steering wheel. All the usual SNES buttons are present, for game starting and functions such as gear changing. Again, the four fire buttons are identified by colour coding.

SNES Mouse Finally, there's the SNES Mouse, supplied with Mario Paint. It's a fairly ordinary two button opto-mechanical mouse with a SNES interface. The two mouse buttons are purple.

SNES Joypad in PlayStation style Here's an example of one game system's design influencing another. It's a SNES joypad, but built in the style of a PlayStation joypad. I found it in a charity shop in Bristol, in its original packaging.

The Sega Mega Drive Joypad

Sega Mega Drive Joypad The Sega Mega Drive was a 68000-based console, and its joypad had three fire buttons. The game-start controls on this machine are reduced to a single ‘Start’ button.

The Sony PlayStation I Joypad

PS1 Joypad A digital joypad with two game-start buttons and eight fire buttons. The Sony PlayStation controller adds more shoulder buttons to the SNES pad, as well as having a even more ergonomic shape. The interface to the console involves a complex protocol but only a few wires.

Namco Neocon controller for PlayStation Here's an alternative controller for the original PlayStation, used mainly for driving games. It's the NeoCon, made by Namco. The controller has a spring-loaded twisting joint in the middle, which lets the player twist the two halves of the controller in opposite directions. This controls the steering in a driving game, while the two red buttons are analog sensors (8-bit resolution) and can control throttle and brake in the game. The left-hand shoulder button is also analog, but the right-hand one is simply a digital switch. Some controllers in the form of steering wheel and pedals seem to emulate the NeoCon, so it's possible that Sony originally specified a generic ‘driving controller’ for games that require it.

ASCII Grip controller for PlayStation Another alternative controller, the ASCII Grip. It's a one-handed controller, suitable for use in either the left or right hand. There are two buttons on the bottom, circle (orange) and cross (blue). On the top of the controller are the square (pink) and triangle (green), duplicated on the left and right, along with the direction pad and all the game-start buttons. What would normally be shoulder buttons are on the lower front face of the controller.

The Atari Jaguar Joypad

Atari Jaguar Joypad A digital joypad with two game-start buttons, three fire buttons, a directional control pad and a numeric keypad. The Atari Jaguar controller was introduced in 1993 and contains a 74LS244 TTL tri-state buffer chip. The fire buttons are labelled ‘A’, ‘B’ and ‘C’ (right to left) and are all red in colour.

The Nintendo Virtual Boy Joypad

Virtual Boy Joypad A digital joypad with two game-start buttons, two fire buttons and two directional control pads. The Virtual Boy controller is unusual in that it also incorporates the machine's batteries (AA size cells), making it rather heavy. Introduced in 1995, the machine was not a great success.

The Sega Saturn Joypad

Saturn Joypad The Sega Saturn controller takes a different approach to reducing the number of wires, by adding a multiplexer. This scheme was introduced in November 1994. The console sends TTL-level signals to the joypad in order to select which of several button inputs will be sent back. Eight button inputs can be read in this manner. The three larger buttons are labelled ‘A’, ‘B’ and ‘C’ while the smaller ones are ‘X’, ‘Y’ and ‘Z’. Thanks to Maarten Foukhar for the photo.

The Nintendo 64 Joypad

N64 Joypad A bizarre three-handled controller, available in several bright colours in addition to the standard grey. Introduced in 1996 and featuring both a digital direction pad and an analogue joystick. The analog-to-digital converter (ADC) for the joystick is loacted within the controller, and only digital signals are sent over the interface. Again, a complex signalling protocol between console and controller. The plug has just three pins, two for power and one signal pin. An optional vibration pack was available that clipped onto the back of the controller. Power for the vibration effect was supplied by a battery in the pack, probably because the motor would draw too much current from the joypad's 3.3V supply.

N64 Joypad

The bright yellow version of the N64 controller.

N64 Joypad The other photo is a third-party controller in black with a quite different design from the original N64 version. Not visible in the photos is the trigger-like fire button located underneath the controller and labelled ‘Z’.

The Sony PlayStation II Joypad

Sony PlayStation II joypad An update to the PlayStation I controller that adds analog controls and a pair of vibration motors. Once again, the analog-to-digital converter (ADC) is in the controller and the interface is digital. The two motors are fitted with eccentric weights of different sizes, and can be independently controlled by the game. The motor with the smaller weight can only be switched on and off, but the larger one can operate at a variable speed as well. For a great example of this, try the game ‘Rez’.

The Sega Dreamcast Joypad

Dreamcast controller The Sega Dreamcast controller includes a slot for the memory card and another slot for an add-on vibration pack. Both these add-ons are install in the photo. Note the colour coding of the buttons; the same colours are used as on the SNES controller, but in different places. There are now two direction pads, one analog (the round one) and the other digital (the cruciform one). Two gun-like triggers are located under the controller.

Dreamcast Arcade Stick Like the NES and SNES, an arcade-style joystick was available as an option. On this version of the controller, all the buttons are green.

The Nintendo GameCube Joypad

GameCube Joypad We come right up-to-date with the GameCube controller, which has both analog and digital controls as well as a vibration motor. Same bit-level protocol as the N64 controller, but sends and receives more bits (25 bits to the controller, 65 bits to the console). Power for the vibration motor is supplied separately at 5V, eliminating the battery that was used in the N64 version.

The Microsoft Xbox Joypad

Xbox Joypad The controllers for the Microsoft Xbox have started some controversy over their size. The U.S. and European controllers are larger than the Japanese version, and some people find the larger type too big. The interface is USB, but with a non-standard connector (a common theme with game controllers). Wireless controllers are available for the Xbox in addition to the standard wired types.

The Microsoft Xbox 360 Joypad

Xbox 360 Joypad The standard controllers for the Microsoft Xbox 360 are wireless, but the photo shows the optional wired type. Not visible in the photo are the two shoulder buttons, in addition to the two triggers. On the front of the controller, there's a tiny connector for what looks like a jack plug (centre) and two two-pin plugs (left and right). The "X" logo lights up to indicate which of the four players this controller belongs to. The black and white buttons of the old Xbox controller are not present on the Xbox 360 version. Also missing are the two connectors for memory modules. The interface is USB, and the vendor/product ID is 045E:028E.

Hand-held Game Controls

Hand-held games tend to have slightly simpler controls than the TV-based consoles. There's usually a four-way joypad and just two fire buttons. Did any hand-held ever include a tilt-operated control? Or a shake-operated one? Need photos: Game Gear, Atari Lynx

The Nintendo Game Boy

Game Boy Joypad The Z80-based Game Boy was first produced in 1989 and was the machine that popularised the game of Tetris. It has the same controls as the NES, namely a four-way joypad, two fire buttons and two game-control buttons. There's no need here to minimise the wiring between joypad and game CPU, simply because they're both in the same box. It's powered by four AA-size cells (the Game Boy Pocket only needed two AAA-size cells). My example is one of the brightly-coloured versions that were produced.

The Nintendo Game Boy Color

Game Boy Color Joypad The Game Boy was updated to incorporate a colour display, and named the Game Boy Color. Same controls as the earlier version, just a direction pad, two fire buttons (‘A’ and ‘B’) and two game-control buttons (‘Select’ and ‘Start’). It's powered by two AA-size cells. My example is one of the brightly-coloured versions.

The Game Park GP32

Game Park GP32 Right up-to-date now with the ARM-based GP32 from Game Park in Korea. Very similar control setup to the Game Boy, though, with Start, Select, A, B and two shoulder buttons, as well as a four-way joypad.

The Nintendo Game Boy Advance SP

Game Boy Advance SP Staying with modern hand-helds, and the ARM chip, this is the Nintendo Game Boy Advance SP. My example is the retro-styled version that imitates the original NES joypad. The controls are familiar from the earlier Game Boy, with the addition of two shoulder buttons (not visible in the photo).
