Gamepad

The original Microsoft SideWinder gamepad had a digital directional pad, six fire buttons, two trigger buttons, and a "Mode" and "Start" button. The original gameport version had a pass-through, so additional joypads or joysticks could be used without unplugging the SideWinder, and also allowed the connection of up to four SideWinder gamepads working simultaneously. Newer USB versions of the SideWinder gamepad have a round digital directional pad instead of the more traditional cross-shaped directional pad, and lack the mode button. The Microsoft SideWinder's button layout is very similar to that of the Sega Saturn

3D Pro

As Microsoft's first SideWinder joystick, the 3D Pro was responsible for setting the overall design as seen in all of Microsoft's future joysticks. Designed as a gaming-neutral joystick, rather than a specialized joystick for use with realistic combat flight simulators, the 3D Pro was built with a functional, but low-key geometric design. Intended to rival the other sticks from the time, the 3D Pro included 8 buttons - 4 on the base, 4 on the stick - an 8-way hat switch, a slider-based throttle, and the stick itself was twist able for Z/rudder/spin control. By going with a geometric design however, it meant the 3D Pro lacked an effective adherence ergonomic principles, making it unsuitable for long gaming sessions for some users.

Electronically, the 3D Pro used a digital/analog hybrid design, that was intended to correct the outstanding flaws in traditional analog joysticks, such as drift and CPU overhead by using a digital/optical tracking mechanism to keep perfect track of the joystick, and a digital communication method over the analog gameport. However, this digital mode required software support, and could not be used with many DOS games at the time (MechWarrior 2 being the only major exception), as most software and gameports were built completely around an analog design.

Additionally, some soundcard gameports, and so-called accelerated game-ports - which attempted to resolve CPU overhead issues presented by polling the gameport directly themselves - such as those produced by Gravis, wouldn't always be able to handle the stick in digital mode.

Fortunately, the 3D Pro had a unique feature in that it could fall-back to an 'analog emulation' mode, where it could emulate either a CH Flightstick Pro or a Thrustmaster FCS (Selectable by a switch on the base), in environments where the digital mode wouldn't work.
In this mode, manual calibration was required, the four base-buttons no longer function and, the joystick would function essentially like a CH Flightstick Pro or Thrustmaster FCS depending on the mode selector switch.

However, on later operating systems the digital mode would be less and less reliable, and on modern PCs most 3D Pro owners can only run in analog mode. Fortunately, the 3D Pro was popular enough to spawn a successor, the Precision Pro, which was a USB device and, while it didn't work in DOS at all, was far more reliable under Windows despite quality issues.

The joystick was widely praised in its inception and was one of the few joysticks with multiple buttons that didn't require a keyboard pass-through. The stick was especially popular with MechWarrior and Descent players as it was one of the few multi-button joysticks supported by the games natively.

The joystick's popularity has created a small die-hard following, with many people still holding onto them despite their age. This resulted in the creation of a USB adapter for the 3D Pro.

Precision Pro 1995

Learning from their past mistakes, Microsoft came up with the SideWinder Precision Pro, correcting the ergonomic issues while fixing some of the electrical issues from the 3D Pro and adding some new features. Ditching the geometric design, the Precision Pro dumped the 3D Pro's stick for one far more ergonomic, correcting the biggest complaint about the original 3D Pro. Microsoft also gave the rest of the Precision Pro a more rounded design, replacing the rectangular base buttons with more rounded buttons, the slider-based throttle with a wheel-based throttle, and the base itself was made more rounded. The Precision Pro also added a shift button to the base, doubling the number of possible button combinations.

Signatures can be seen inside the joystick, on the base coverplate. Fred Iyc and Edie Adams (User Experience Manager, Microsoft: http://www.affectivedesign.org/archives/151) are among the 17 people who have signed it.

For its electronics, the Precision Pro featured a refined hybrid system, resolving some of the hardware compatibility issues with the 3D Pro. However, with the widespread introduction of USB in consumer computers shortly after the Precision Pro was released, Microsoft soon re-released the joystick in a USB-compatible form (joysticks labeled as Part No. X03-57540, Product I.D. 85791-...). The revised joystick still featured a gameport connector but had additional circuitry for interfacing with USB, and was bundled with a USB converter (a DIY converter project exists). Original Precision Pros remain incompatible with this converter, a user made converter exists though. The creation of the USB converter bypassed the problems with the analog gameport entirely, and as a result became the true solution to the electrical problems. However, due to a flaw in the design of the Precision Pro, in rare cases the stick would build up a static charge in its electronics and require either a complex process to discharge that was not always successful, or simply needed to stay unpowered for a number of hours to slowly discharge on its own. This is also one of the first joysticks to use light sensors instead of potentiometers so it required no calibration, and thus had no electronical moving parts. The only moving parts were mechanical on the throttle and joystick pivots which gave this joystick virtually unlimited lifetime. The Precision Pro 2 had reintroduced potentiometers to save money and thus their lifetime was limited to wear and tear of the potentiometers.

Thanks to the timing of the launch of the Precision Pro to coincide with the widespread launch of USB along the ergonomic corrections and rarity of the static charge problem, the Precision Pro saw a much higher sales volume and review scores than the earlier 3D Pro.

Force Feedback Pro

With the launch of the Precision Pro, Microsoft decided to also enter the fray of force feedback joysticks, with the introduction of the Force Feedback Pro. Built on the design of the Precision Pro, the Force Feedback Pro differed only in the inclusion of motors for the force feedback effects, and the lack of USB compatibility. Due to the inclusion of the motors, the Force Feedback Pro was significantly larger and heavier than the Precision Pro, making it easy to differentiate between the two.

Precision 2

The basis of Microsoft's last generation of SideWinder joysticks, the Precision 2 design was a further refinement of the previous Precision Pro. Compared to the Precision Pro, the Precision 2 dropped the Pro's shift button, replaced the throttle wheel with a more traditional lever, and rearranged the face buttons on the stick in to a symmetric design. The Precision 2 also dropped all gameport compatibility by only shipping in a USB version, and was slightly smaller and lighter than the Pro. Unfortunately, in spite of being Microsoft's 2nd-generation USB controller, the Precision 2 in particular seemed to suffer more from the USB SideWinder's long-standing static buildup problem than the original Precision Pro.

Force Feedback 2

Along with replacing the Precision Pro with a new design, the Force Feedback Pro was replaced with a Precision 2 derivative, the Force Feedback 2. Compared to the Force Feedback Pro and the Precision 2, nothing new was added to the Force Feedback 2 that wasn't added to the Precision 2, in fact the shift button was taken away. The overall size and weight difference was not so great with the use of smaller motors. This joystick came in two varieties: one version with a silver trigger, and an updated version with a translucent red trigger. One of the main ideas in the Force Feedback 2 was the removal of the power brick.

Joystick

Using the Precision 2 design once again, Microsoft introduced a value-oriented SideWinder joystick, simply called the SideWinder Joystick. In spite of its value designation, the SideWinder Joystick was functionally nearly the same as the Precision 2. The only feature dropped was the 8-way hat switch, otherwise the differences were cosmetic, including shrinking the base, moving the throttle to the front of the base, and replacing 2 of the rounded buttons on the stick with more rectangular buttons.

. It was the first wheel controller to contain force feedback. It lacks proper driver support for Windows Vista and Windows 7.

Strategic Commander

The Strategic Commander is designed to complement a standard mouse/keyboard setup for Real Time Strategy games. It features a total of 6 programmable command buttons, 2 zoom buttons, 3 shift buttons, a macro record button and a 3-point configuration switch. The device also has three movement axes; X, Y and Z (rotation). Through extensive configuration of the shift and command buttons, it is possible to create a total of 24 different commands per configuration.

The Strategic Commander is a highly ergonomic device, and resembles a large mouse in shape, contoured for the left hand. It has an upper section attached to a base. On the upper section, the programmable buttons mentioned above are located near the tips of the index, middle and ring fingers for quick access. Three buttons are located near the thumb in an arc.

A feature of the device is that the upper section is also a 2-axis motion controller with additional support for rotation. It allows motion in the X, Y & Z axis (corresponding to Forward, Backwards, Strafe left & right, Turn left & right). This made it an ideal companion for FPS and similar games; because you can aim weapons or look up and down with the right hand while simultaneously slewing position with the left hand, and change weapons etc. with the left finger buttons.

Software was included for the device to provide hotkeys for a number of (then popular) games. The buttons are also programmable, allowing the device to be used with other games and applications. For example, one interesting application developed at Carnegie Mellon used the device as a peripheral for navigating massive social network

 using programmable macros.

The package included a headset with an attached microphone, though these could be substituted with any other PC headset/microphone. The puck acted as an intermediary between the sound card and the sound input/output devices. The headset, along with the system speakers, plugged into the puck, where a switch could be used to set whether sound would be output from the speakers or the headset. The puck also had its own volume control. To provide power for the puck LEDs and drive the voice command and channel functions, a USB connection was also required.

Microsoft discontinued the product in 2003. By then, the market for voice chat had seen intense competition from downloadable and free-to-use software like Ventrilo

, among others. These software packages only charge the host or server, whereas each person would have to own a Game Voice in order to use the hardware and software. As a result, the Game Voice ultimately lost that market. However, these competing software packages do not offer voice command systems.

Microsoft has not released the hardware specifications so that an open source driver could be developed. The device is supported under Windows XP, but no new driver is planned for Windows Vista. Fortunately Linux can use this HID device using various third party applets (i.e. Kamevoice)

Freestyle Pro

The Freestyle Pro, released in 1998, was a rather novel gamepad, as the up-down-left-right directions in analogue mode were controlled by the movement of the controller, more precisely by the absolute pitch and roll position of the pad. This reaction on movement is quite similar to some of the features of the new Sony PlayStation 3 SIXAXIS. Games that did not punish washy control inputs such as Motocross Madness

s) couldn't be controlled precisely with it - as movement was free and not limited by physical bounds as in a traditional analogue joystick/gamepad design, the user could not intuitively say if he moved the controller 100, 50, etc. percent in one direction. Even the "zero position" could not be precisely found, as retracting mechanisms could obviously not be built in.

The control pad had a total of ten digital fire buttons: six buttons controlled with the right thumb (named ABC XYZ), two shoulder buttons (one left, one right), and two buttons controlled with the left thumb, one named start, the other marked with a shift key

The left thumb also controlled a D-pad

 which was rather useless when it came to fast and precise digital movement controls: the D-pad had to be pushed a far way until the action requested was finally registered, and the directions pressed were interpreted too washy (pressing left often resulted in the controller registering a diagonal left-down, for example - a problem that is crucial in versus fighting games).
The endless steps throttle in the middle was also not perfectly thought-out: it behaved like an endless scroll wheel

 on the mechanical side, while the hardware driver assumed it to be an absolute value throttle – scrolling on and on in one direction only caused the hardware driver to rest in either zero percent or 100 percent throttle position.

) and digital mode (red LED). In analogue mode, the x- and y-axis were controlled by the analogue controller movements, and the D-pad was used as a hat switch. In digital mode, the D-pad controlled the x- and y-axis like a traditional digital control pad (therefore, there was no hat switch function in digital mode).

Due to the release in 1998, at which time USB was just taking off, the Freestyle Pro supported both game port

 and USB connection. Without the adapter, the controller's cable ended in a game port plug. The sale box contained the Gameport-to-USB adapter for free.

Dual Strike

The Dual Strike, which debuted in 1999, was Microsoft's second notable venture into strange gamepad designs, following the Freestyle Pro. The Dual Strike attempted to blend both mouse and gamepad functions into a single unit. It was composed of two portions; there is a hinge between the two that allows you to rotate the right side up and down and from side to side. The Dual Strike only supported USB.

SideWinder gaming mouse and keyboard

In 2007, following a collaboration with Razer

Razer is a privately held computer peripherals manufacturer specializing in products specifically marketed to gamers.Razer's main slogan is 'FOR GAMERS, BY GAMERS'....

in creating the Microsoft Habu and Microsoft Reclusa, a gaming mouse and gaming keyboard sold under the plain Microsoft Hardware brand, Microsoft resurrected the SideWinder brand with an all-new SideWinder Mouse, designed from the ground up for high-end PC gaming. The design incorporated a number of advanced features including adjustable weights, programmable macro mode, on- the- fly DPI change, and a built-in LCD display, the first ever found in a mouse.

In 2008, Microsoft also released the SideWinder X6 Gaming Keyboard, which is designed to be the keyboard counter-part of the Sidewinder Mouse. It features up to 30 programmable macro keys, volume control, media control, a detachable numpad and backlighting. Along with this keyboard a new mouse was released dubbed the SideWinder X5. The X5 has a more basic functionset then its predecessor but was well received because of its lower price. Its shape is the same as the original but without the LCD, weight adjusting and metal side buttons. It also comes with a complete black design with red "LED Jets" on the back to make it stand out from the original and better fit the X6 keyboard.

In February 2009, Microsoft released another update to the SideWinder line, the SideWinder X8 gaming mouse. This new iteration incorporated new Microsoft BlueTrack tracking technology, intended to provide better tracking on non-standard surfaces. In addition, the mouse was made wireless, and the maximum DPI sensitivity was upped to 4000.http://gizmodo.com/5047897/sidewinder-x8-wireless-gaming-mouse-has-ridiculous-4000dpi-still-designed-by-darth-nerd

In March 2010, Microsoft released a second gaming keyboard, the Sidewinder X4. In comparison with the earlier X6, anti-ghosting technology was added. However, USB ports and the detachable numpad were removed.
