What is the Atari Jaguar/Jaguar64? A. The world's first 64-bit home console video game system. Developed after three years of research, manufactured by IBM, the Jaguar offers high-speed action, spectacular graphic effects, and CD-quality sound. The console's name was originally "Jaguar." In the middle of 1995, Atari formally changed the name to "Jaguar64." For the sake of simplicity in this document, the term "Jaguar" will be used to refer to the console. ======================================================================== ====== Q. What do I get when I buy a Jaguar? A. The Jaguar package has a suggested retail price of $99, and contains the Jaguar itself, one controller, an AC adapter, and a television RF switch box. There are plans to re-introduce the "console and game" package in the future, but for now, you have to buy a game separately. ======================================================================== ====== Q. How does IBM fit into this? A. IBM has a $500 million contract with Atari Corp. to assemble, test, package, and distribute Jaguar units. Manufacturing is done at IBM's Charlotte, NC facility, and the Jaguar is IBM's first attempt at producing a consumer grade product for an outside vendor. Specifically, Jaguar circuit boards are manufactured and assembled by an IBM subcontractor; IBM cases, tests, and packages final Jaguar units; units are then sent to Atari for distribution. IBM has no known participation in the design of the Jaguar. IBM has no plans to create games for the Jaguar. As of mid-1994, Jaguar units are also manufactured by Comptronix in Colorado Springs. ======================================================================== ====== Q. Okay, who did design the Jaguar? A. The primary designers of the Jaguar are Martin Brennan and John Mathieson. They started their own company in 1986 called Flare 1, and designed an original multiprocessor game console. After the system was finished, Flare wanted to "evolve" the system, but needed funding for the job. Atari was contacted, believed in the idea, and agreed to participate. Atari, Brennan, and Mathieson started a new company called Flare 2 to develop the system. As Jaguar development moved along, it became apparent that the machine would leapfrog the new systems from Nintendo and Sega, so they decided to bring the machine to light. The entire process took three years, from initial design to production-ready models. The proprietary chips are manufactured by Toshiba and Motorola. ======================================================================== ====== Q. What are the specifications of the Jaguar? A. Physical dimensions: Size: 9.5" x 10" x 2.5" Controls: Power on/off Display: Programmable screen resolution. Horizontal resolution is dependent on the amount of scanline buffer space given to the "Tom" graphics processor. Maximum vertical resolution varies according to the refresh rate (NTSC or PAL). Reportedly, a stock Jaguar (without additional memory) running NTSC can display up to 576 rows of pixels. 24-bit "True Color" display with 16,777,216 colors simultaneously (additional 8 bits of supplimental graphics data support possible) Multiple-resolution, multiple-color depth objects (monochrome, 2-bit, 4-bit, 8-bit, 16-bit, 24-bit) can be used simultaneously Ports: Cartridge slot/expansion port (32 bits) RF video output Video edge connector (video/audio output) (supports NTSC and PAL; provides S-Video, Composite, RGB outputs, accessible by optional add-on connector) Two controller ports Digital Signal Processor port (includes high-speed synchronous serial input/output) Controllers: Eight-directional joypad Size 6.25" x 5" x 1.6", cord 7 feet Three fire buttons (A, B, C) Pause and Option buttons 12-key keypad (accepts game-specific overlays) The Jaguar has five processors, which are contained in three chips. Two of the chips are proprietary designs, nicknamed "Tom" and "Jerry". The third chip is a standard Motorola 68000 used as a coprocessor. Tom and Jerry are built using an 0.5 micron silicon process. With proper programming, all five processors can run in parallel. - "Tom" - 750,000 transistors, 208 pins - Graphics Processing Unit (processor #1) - 32-bit RISC architecture (32/64 processor) - 64 registers of 32 bits wide - Has access to all 64 bits of the system bus - Can read 64 bits of data in one instruction - Rated at 26.591 MIPS (million instructions per second) - Runs at 26.591 MHz - 4K bytes of zero wait-state internal SRAM - Performs a wide range of high-speed graphic effects - Programmable - Object processor (processor #2) - 64-bit RISC architecture - 64-bit wide registers - Programmable processor that can act as a variety of different video architectures, such as a sprite engine, a pixel-mapped display, a character-mapped system, and others. - Blitter (processor #3) - 64-bit RISC architecture - 64-bit wide registers - Performs high-speed logical operations - Hardware support for Z-buffering and Gouraud shading - DRAM memory controller - 64 bits - Accesses the DRAM directly - "Jerry" - 600,000 transistors, 144 pins - Digital Signal Processor (processor #4) - 32 bits (32-bit registers) - Rated at 26.6 MIPS (million instructions per second) - Runs at 26.6 MHz - Same RISC core as the Graphics Processing Unit - Not limited to sound generation - 8K bytes of zero wait-state internal SRAM - CD-quality sound (16-bit stereo) - Number of sound channels limited by software - Two DACs (stereo) convert digital data to analog sound signals - Full stereo capabilities - Wavetable synthesis, FM synthesis, FM Sample synthesis, and AM synthesis - A clock control block, incorporating timers, and a UART - Joystick control - Motorola 68000 (processor #5) - Runs at 13.295MHz - General purpose control processor Communication is performed with a high speed 64-bit data bus, rated at 106.364 megabytes/second. The 68000 is only able to access 16 bits of this bus at a time. The Jaguar contains two megabytes (16 megabits) of fast page-mode DRAM, in four chips with 512 K each. Game cartridges can support up to six megabytes (48 megabits) of information, and can contain an EEPROM (electrically erasable/programmable read-only memory) chip to save game information and settings. Up to 100,000 writes can be performed with the EEPROM; after that, future writes may not be saved (performance varies widely, but 100,000 is a guaranteed minimum). Depending on use, this limit should take from 10 to 50 years to reach. The Jaguar uses 24-bit addressing, and is reportedly capable of accessing data as follows: Six megabytes cartridge ROM Eight megabytes DRAM Two megabytes miscellaneous/expansion All of the processors can access the main DRAM memory area directly. The Digital Signal Processor and the Graphics Processor can execute code out of either their internal caches, or out of main memory. The only limitations are that (1) "jump" instructions in main memory have certain restrictions; the JMP (unconditional jump) command is longword-aligned, while the JR (jump-indexed-by-register) command must be either word- or longword- aligned. And (2) running out of the cache is much faster (up to four times faster) and efficient. Some believe that the inability to jump/branch in main memory makes the main memory feature useless. Swapping data between the caches and the main memory is a quick, low overhead operation, and therefore the main memory is often used as "swap space" for cache code. The RISC compiler now included in the Jaguar developer's kit produces code that transparently swaps code through the cache. This effectively lets developers write RISC code without concern for the cache size limits. Compressed cartridge data can be uncompressed in real-time, and ratios of up to 14:1 have been cited. In theory, a Jaguar cartridge can store up to 84 megabytes (672 megabits) of data, though actual results will vary widely (most often, images are compressed, while sound and code are not). Compression is performed with BPEG, an enhanced JPEG image decompression mechanism. BPEG supercedes the former JagPEG algorithm, working up to 10 times faster and with more flexibility. Other Jaguar features: - Support for ComLynx I/O for communications with the Atari Lynx hand-held game system and networked multiconsole games (on DSP port, accessible by optional add-on connector). Networking of up to 32 Jaguar units available. - The two controller ports can be expanded to support "dozens" of controllers - Digital and analog interfaces - Keyboards, mice, and light guns are possible - Expansion port allows connection to cable TV and other networks - Digital Signal Processor port allows connection to modems and digital audio peripherals (such as DAT players) - One megabyte per second serial interface - 9600 baud, RS-232 serial port (accessible with optional interface) - General-purpose I/O bits via the cartridge port - Can accomodate future expansions of different processor types, I/O types, video types, and memory types and/or quantities. ======================================================================== ====== Q. Is the Jaguar really a 64-bit system? A. The question is hard to resolve, largely because the definition of what constitutes an "N-bit" system has not been set. Of the five processors in the Jaguar, only the object processor and the blitter are "true" 64-bit components. Because the blitter and the object processor are in the Tom chip, by extension Tom is a 64-bit chip. The Jaguar also uses a 64-bit memory architecture, according to Jez San of Argonaut Software. Some say the Jaguar should be considered a 32-bit system, as that is the maximum register size in the programmable processors (the 68000, the graphics processor, and the DMA sound processor). Others say the Jaguar can be considered a 64-bit system, because 64-bit components are used, and the GPU can access 64 bits of data if required. Again, the lack of an agreed-upon definition serves to complicate the issue. According to Jaguar designer John Mathieson, "Jaguar has a 64-bit memory interface to get a high bandwidth out of cheap DRAM. ... Where the system needs to be 64 bit then it is 64 bit, so the Object Processor, which takes data from DRAM and builds the display is 64 bit; and the blitter, which does all the 3D rendering, screen clearing, and pixel shuffling, is 64 bit. Where the system does not need to be 64 bit, it isn't. There is no point in a 64 bit address space in a games console! 3D calculations and audio processing do not generally use 64-bit numbers, so there would be no advantage to 64 bit processors for this. "Jaguar has the data shifting power of a 64 bit system, which is what matters for games, so can reasonably be considered a 64 bit system. But that doesn't mean it has to be 64 bits throughout." For the record, the opinion of most third party developers and observers is that the Jaguar is indeed a 64-bit system. The emphasis is on the word "system"; while not every component is 64 bits, the Jaguar architecture, as a COMPLETE SYSTEM, is. ======================================================================== ====== Q. The Jaguar uses a 68000. Isn't that the CPU? A. Again, quoting from Jaguar designer John Mathieson, "It may be the CPU in the sense that it's the centre of operation, and boot-straps the machine, and starts everything else going; however, it is not the centre of Jaguar's power. ... The 68000 is like a manager who does no real work, but tells everybody else what to do." And... "Atari were keen to use a 68K family device, and we looked closely at various members. We did actually build a couple of 68030 versions of the early beta developers systems, and for a while were going to use a 68020. However, this turned out too expensive. We also considered the possibility of no [Motorola 680x0 chip] at all. I always felt it was important to have some normal processor, to give developers a warm feeling when they start. The 68K is inexpensive and does that job well. I maintain that it's only there to read the joysticks." ======================================================================== ====== Q. How can a graphics processor be the CPU? A. The 64-bit custom graphics chip is a good general purpose RISC unit, but it has been optimized for graphics work. Developers are free to specify which processor(s) to use in a program, as desired. ======================================================================== ====== Q. What kind of special effects can the Jaguar do? A. The Jaguar is capable of doing the following visual effects: - High-speed scrolling (Object Processor). - Texture mapping on two- and three-dimensional objects (GPU and Blitter). - Morphing one object into another object (GPU). - Scaling, rotation, distortion, and skewing of sprites and images (Object Processor). - Lighting and shading from single and multiple light sources (GPU and Blitter). - Transparency (Object Processor). - "Rendering" up to 850 million one-bit pixels/second (35 million 24-bit pixels/second, 26 million 32-bit pixels/second), or 50 million Goroud shaded pixels/second. "Rendering" is believed to mean transferring a pixel from a frame buffer to the screen. - Sprites of "unlimited" size and quantity. Realistically, sprites can be over 1,000 pixels wide/tall, and the number of sprites allowed is limited by processor cycles instead of a fixed value in hardware (Object processor). - Programmable screen resolutions, from 160 to 800 pixels per line. The resolution can be increased even further with additional hardware up to a reported 1350 pixels per line. One of the Jaguar modes is called "CRY mode", which supports lighting and effects in 3D graphics. Red, green, and blue color elements are ranged from 0 to 255, and the lighting level for any pixel can be changed by setting one byte linearly. E.g., the relative proportions of red, blue, and green are indicated with one byte, while a second byte selects an overall intensity of 0 to 255. CRY allows much smoother shading of single colors, but doesn't allow blending between colors as smoothly. Actual graphics performance is hard to measure, as there are no industry- standard benchmarks. Rebellion Software has claimed that the Jaguar can render "10,000 Gourard shaded, large, 65536 color, any shape polygons per second," while still performing other tasks. Presumably this level can be increased further with optimized programming. ======================================================================== ====== Q. How come the Jaguar claims to have "32-bit" graphics, when 16 million colors only need 24 bits for rendering? A. The additional 8-bits is for programmers to implement whatever visual effects may be desired. Examples cited include Z-buffering (for polygon graphics) and an alpha channel (for transparency). ======================================================================== ====== Q.

The games are downloaded to the customer and played at home, and game instructions can be printed with additional equipment. Details are available from local FSN service providers. ======================================================================== ====== Q. What's the information on the CD-ROM drive? A. A double-speed CD-ROM drive is available. The CD drive has an access time of 210 milliseconds, and has a sustained data transfer rate of 352.8K per second. The CD-ROM drive features a modified data bus interface for access to the Tom and Jerry chips almost directly, allowing for a higher throughput rate on sound and graphics. Storage on a disc is approximately 790 megabytes (6,320 megabits). The CD-ROM drive plugs into the Jaguar's cartridge slot. A pass-through cartridge slot allows cartridges to be used with the CD-ROM attached. Separate memory cartridges allow Jaguar CD games to be saved for later play. The Jaguar CD allows delivery of full-screen, full-motion video. The CinePak video decompression system has been licensed from SuperMac Technologies. It is a 7K routine in the GPU and can be included in any CD-ROM software that needs it, allowing full-screen video at 24 frames per second. Movie quality pictures can then be overlaid on the screen with computer generated graphics if the game demands it. Time-Warner has licensed a library of film clips from its movies to Atari. The Jaguar CD has "Virtual Light Machine" built in. This program plays audio CDs and generate accompanying color and visual effects that react to the music and sounds. The user can control and select effects with the Jaguar controller. Regular audio CD playback features (volume control, track programming, etc.) are also available. The Jaguar CD can also display CD+Graphics discs. Supplimental cartridges for Kodak PhotoCD and MPEG-1 (Motion Picture Experts Group) compression are being considered. The MPEG cartridge will reportedly include extra RAM for buffering and support the whitebook video format. The drive is being manufactured by Philips in the United States. Its dimensions are 6.5" x 10.5" x 3.5", and it weighs 1 pound, 10 ounces. The price is $150, and includes the TEMPEST 2000 soundtrack audio disc, a sampler for the CD game MYST, and two CD-ROM games: VID GRID and BLUE LIGHTNING. ======================================================================== ====== Q. What's the information on the virtual reality headset? A. Atari Corp. and the Virtuality Group had signed a contract whereupon Virtuality would develop virtual reality hwardware and software for the Jaguar. In return, Virtuality would get the rights to port Jaguar VR games to their Virtuality arcade consoles. As of December 1995, the status of the Jaguar VR is on indefinite hold. Unofficial reports conflict on whether the unit has been cancelled, suspended, and/or reworked. Reasons given for the action range from Atari's needs to reassess their investments and focus on core business, to the high price of the Jaguar VR headset, to Virtuality's problems in trying to create a mass-market headset that could track head movement fast enough to avoid motion sickness after a few minutes of play. As originally reported, the Jaguar VR package consists of two components: (1) A lightweight headset (weighs less than one pound). It can be adjusted for fit and works with or without glasses. Game graphics are provided by a single 7", TFT active-matrix color LCD screen, with a resolution of 260 by 400 pixels and up to 65,000 colors. Dual temple speakers provide sound, and a built-in microphone allows player communication in future networked games. A custom optical system projects a binocular image to both eyes; it is aligned at infinity, so focus adjustment is not needed. Two degrees of freedom (left/right and up/down) are available. Field of view is 52 degrees horizontal by 40 degrees vertical. (2) A tabletop-mounted tracking station. The station senses the position of the controller and the headset with "V-Trak" infra-red tracking. The tracking speed is 250 Hz, with a lag time of 4 milliseconds, four times faster than Virtuality's arcade hardware. The tracker has a range of approximately 100 degrees; multiple trackers can be daisy- chained together to provide a complete 360-degree tracking range, but most Jaguar VR games will not require a full 360 degrees. The Jaguar VR equipment is designed to be played while sitting down, so as tp avoid injuries. if a player moves out of the tracking station's range, a safety cutoff is triggered to suspend the game. Jaguar VR games will be written for use with the regular controller, as well as a two-button "virtual gun" hand-held joystick. The licensing agreement between Atari and Virtuality permits authorized Jaguar third- party software developers to write their own VR titles. ======================================================================== ====== Q. What's this "Panther" I hear about? A. Quick history lesson: Sometime in the late 1980s, Atari Corp. was doing research and development on "next generation" video game consoles. There were two systems, a 32-bit machine called the Panther, and a 64-bit machine called the Jaguar. It is reported that work on the Jaguar was progressing better/faster than expected, so Atari abandoned the Panther to focus their energies on the Jaguar instead. Supposedly, if both machines were fully developed, the Jaguar would have followed the Panther only two years later. Reports of development work on the Panther have been whispered since 1988; some people have erroneously mistaken those rumors to be about the Jaguar. The Panther reportedly was considered a "32-bit" machine by Atari, though for reasons unknown. It featured three chips, consisting of a Motorola 68000 running at 16Mhz, an object processor called the Panther, and an Ensoniq sound processor called Otis, featuring 32 sound channels. The Panther could supposedly display 8,192 colors from a palette of 262,144 colors, and could display 65,535 sprites of any size simultaneously. ======================================================================== ====== Q. What's this "Jaguar II" I hear about? A. There's been a little confusion with this topic, since at least two separate machines have been called a "Jaguar II." The first was to have been an integrated Jaguar/Jaguar CD-ROM unit. That project has since been cancelled, making the point moot. The other Jaguar II is Atari's next video-game console. It is currently still in the design phases at this moment, so solid details are hard to come by. The following information has been RUMORED, however: * Main chipset (codename "Midsummer") being developed by Motorola. * Fully backwards compatable with the existing Jaguar. Will be able to play all games and use all peripherals. * Processing speed "two to four times faster than the Sony PlayStation." * Full C/C++ development package available. At any rate, given the usual development time for new hardware, don't expect to see a Jaguar II until 1997 at the earliest. All video-game companies are always developing new hardware, and the Jaguar II is probably just Atari's equivalent to everyone else's "future works." ======================================================================== ====== Q. Is there a difference in Jaguar games/units sold in different countries? Do I need to keep track of PAL and NTSC versions of a game? A. There is no difference in the Jaguar game software. A properly-written Jaguar game detects PAL or NTSC at startup and changes the playfield size and game speeds accordingly. A properly-written Jaguar game will run at the same speed on either machine. There are no regional or national market lock-outs as there are for other game consoles. The Jaguar consoles themselves are configured differently, according to the country they are sold in. The primary differences are in the video output format (NTSC or PAL) and the power adapters (110 volt or 220 volt). For example, to use an American-market Jaguar in Europe, you need a 220 volt-to-110 volt adapter (readily available) and a SCART television set to accept the Jaguar's RGB signals. Some European TV sets may also require changing the Jaguar display from a 60Hz frame rate to 50Hz. The 50Hz/60Hz frame rate is set by soldering pads on the bottom of the Jaguar PCB. On an NTSC Jaguar, they're located on the bottom of the PCB near the controller ports. The set labelled "R140" determines between 50Hz and 60Hz. Connect the two points for 50Hz, or leave them disconnected for 60Hz, as follows: 60Hz 50Hz o-o R135 o-o o o R136 o o (Information courtesy of Martin Zimmer, o o R137 o o marz@haari.mayn.sub.de) o o R140 o-o PAL Jaguars sold in Europe have the R140 pads connected with a zero ohm SMD resistor, which can be removed with a soldering iron. It is possible to wire a switch to the points, allowing the Jaguar to be toggled between 50Hz/60Hz. This is mainly useful for PAL Jaguars to play games at the original speed and screen resolution of the NTSC version. % Russ Juckes (RussHype@digibank.demon.co.uk) gives these instructions for % finding the pads on a European/PAL Jaguar: % % "Hold the Jaguar PCB with the Joystick ports to the bottom. On the % underside of the board, near the joystick ports, and to the left of centre % there are four links, the top and the bottom one bridged. (Both with zero % ohm resistors). Above them there is another link, with a brown resistor. % % "The bottom link is the one that needs to be broken. I used a penknife to % scratch away the solder, and then a needle-nosed pair of pliers to break % the resistor. % % "The links are *not* labelled in any way. As another guide to make sure % you are about to snip the correct link, they are placed directly underneath % a chip (which is obviously on the top of the PCB!) so if you use a soldering % iron, be careful!" ======================================================================== ====== Q. Hey! My Jaguar makes a quiet hissing sound! What's going on? Is it dangerous? A. Atari has cited several reasons for the hissing noise. Some have said that the sound is from the RF generator. The RF shield has holes in it (ostensibly to help air flow and keep the unit cool), and it is believed that the holes produce the noise. Others say the sounds are produced by coil L29 which is responsible for the proper voltage regulation to +10.0V, together with U38. The coil's copper wire vibrates when the current through it changes abruptly, making the hiss. There are two solutions: 1) Use plastic spray or silicone rubber glue to fix the coil's wire. 2) Replace the original Jaguar power-supply with a variable power-source, using 7.5V DC instead of 9V DC (it is not certain whether the Jaguar CD will require 9V DC, which would make this "fix" unworkable with the CD drive). In any case, the "hissing" noise is not dangerous, but merely annoying. It is usually audible only if you put your ear next to the unit and listen closely, and is not interference in the audio output. It is roughly analogous to the buzz made by electric clocks. Later Jaguars do not have this problem. ======================================================================== ====== Q. My Jaguar comes up with a red screen instead of a game! Is it broken? A. Most often, the "red screen" problem appears after the Jaguar logo has disappeared off the TV screen, and is caused by one of the following: 1. Poor contact between the Jaguar and the cartridge (most likely). Make sure that the cartridge is firmly seated in the cartridge slot, and that contacts are not dirty/dusty. 2. Bent pins in the cartridge slot (rare). This may be caused by rough edges on some cartridges. The pins should be carefully straightened. 3. Defective cartridge (rare). If the red screen only appears with one cartridge but not others, the game may be defective. Exchange it for another. If the Jaguar logo appears without problems, then the Jaguar is probably working fine, and it's only the data transfer between the unit and the cartridge that's causing the problem. ======================================================================== ====== Q: What's the wiring schematic for the Jaguar controller? A: Uwe Roeger (uwer@aragon.bb.bawue.de) reverse-engineered the Jaguar controller port and dissected a Jaguar controller to provide the following circuit diagram: Padport 4 Padport 3 Padport 2 Padport 1 (yellow) (orange) (red) (brown) 74HC244 | | | | ______ | | | | R1 4k7 | | | | | | | | | Padport 6 Pause -------|----------|----------|----------+----- 2| -|)- |18- (blue) | | | | | | | +---|------+---|------+---|------+ R2 4k7 | | | | | | | | | | | | | Padport 10 "A"--|<-+ "B"--|<-+ "C"--|<-+ Opt -|<-+---+----- 4| -|)- |16- (black) | | | | | | | +---|------+---|------+---|------+ R3 4k7 | | | | | | | | | | | | | Padport 11 Right-|<-+ "1"--|<-+ "2"--|<-+ "3"--|<-+---+----- 6| -|)- |14- (grey) | | | | | | | +---|------+---|------+---|------+ R4 4k7 | | | | | | | | | | | | | Padport 12 Left -|<-+ "4"--|<-+ "5"--|<-+ "6"--|<-+---+----- 8| -|)- |12- (l.blue) | | | | | | | +---|------+---|------+---|------+ R5 4k7 | | | | | | | | | | | | | Padport 13 Down -|<-+ "7"--|<-+ "8"--|<-+ "9"--|<-+---+-----11| -|)- |9-- (pink) | | | | | | | +---|------+---|------+---|------+ R6 4k7 | | | | | | | | | | | | | Padport 14 Up --|<-+ "*"--|<-+ "0"--|<-+ "#"--|<-+---+-----13| -|)- |7-- (white) |______| Padport 9: Ground (violet) -- Pin 1,10,15,17,19 on 74HC244 Padport 7: +5 VDC (green) -- Pin 20 on 74HC244 SYMBOL KEY ========== --|<-- 1N4148 Diode + Wire connexion Rx 4k7 Standard resistor, 4700 Ohms, .25 Watts (all resistors are pull-ups; i.e. tied to +5VDC on one end) Padport numbers correspond to those on a standard 15-pin SUB-D plug. The colors of the wires may be different in other versions of the controller. ======================================================================== ====== Q. What's this about a rotary controller? What games use it? How do I make one for myself? A. TEMPEST 2000 has hidden in it an option for a rotary controller (at the "Game Options" menu, press Pause on both controllers to activate the "Controller Type"). No plans for an official Atari rotary controller have been announced, but many TEMPEST fans have been trying to build such a controller, to give the game a feel that's close to its arcade original. Andy Light has written instructions for taking a Jaguar joypad and an Atari 2600 Driving Controller and building a rotary controller with the parts. His instructions are condensed below. READ THE INSTRUCTIONS THOROUGHLY BEFORE ASSEMBLY -- there are some areas that are left to the whim of the builder, and advance planning is highly recommended. ANDY LIGHT'S JAGUAR ROTARY CONTROLLER INSTRUCTIONS Parts needed: Atari Jaguar controller Atari 2600 Driving Controller (NOT the paddles) 13 wires, preferably of separate colors Buttons A board or box or shell to mount everything on/in 1. Open the driving controller by removing the two underside screws. Inside is a top-like device or a grey box with three wires coming out of it. This is the encoder. Pull the driving controller's knob off the encoder's shaft, then remove the encoder by unscrewing the nut that holds it in place. Disconnect the wires from the encoder. 2. Open the Jaguar controller. There are four screws on the bottom holding it together, behind the round rubber pads. Inside the controller are two circuit boards connected by a ribbon of wires. The bottom board is for the numeric keypad and is held by two screws. Remove the screws and take out the keypad. 3. Disconnect the wire ribbon from the keypad by melting the solder. CAREFUL! This is delicate work -- get help if you need it. Solder the thirteen wires where the ribbon connection was; do not confuse them. 4. From the left side of the board (the side that says "P2"), I've numbered the wires as follows: 1) Common 5) Button A 9) Button C 13) Down 2) Right 6) Button B 10) Pause 3) Option 7) Button B 11) Up 4) Option 8) Button C 12) Left 5. On the encoder, connect wire #1 to the center terminal, #2 to the right terminal, and #12 to the left terminal. The rotary part of the controller is now finished. 6. How to connect the other controls is up to you. I'm using arcade buttons, a thumbpad, and a switch (to toggle joypad or rotary control) mounted in an Atari 5200 trak-ball controller case. You can mount a joystick, extra buttons, or other features for your own controller. Buttons and empty control boxes are available at stores such as Radio Shack. Wiring for the other signals are as follows: Up - wires #1 and #11 Button A - wires #1 and #5 Down - wires #1 and #13 Button B - wires #6 and #7 Pause - wires #1 and #10 Button C - wires #8 and #9 Option - wires #3 and #4 Because wire #1 has multiple uses, you will either need to string it or split it for each destination. 7. Reassemble and mount everything according to your design. For better spin, you can glue lead fishing sinkers to the inside of the knob, and lubricate the shaft of the encoder with light oil or silicone lubricant. That's it! Please forgive me for any mistakes in my grammer, terminology, spelling, etc. If you encounter any problems, feel free to e-mail me at ALIGHT55@AOL.COM. Good luck! ======================================================================== ====== Q. I want something better than RF output from my Jaguar. What do I do? A. Atari has an S-Video cable and a Composite video cable available for use with the Jaguar. See the "Peripherals" section for details.
