There are currently four types of ATARI Video Computer Systems. The original model (2600) is composed of two PC Boards connected by a 12-pin ribbon cable with the motherboard surrounded by a heavy aluminum casting. The other models (2600A: Revisions 1-13, Revisions 14-15, and Revisions 16 and up) are composed of a single board with a light aluminum shield. The single board models differ slightly in the video output circuitry. ...

the RF radiation shielded motherboard. Outer Cast inq The casting consists of three pieces of plastic (see Figure 1-2). The pieces include t h e base, which holds the switchboard and motherboard assembly; the top; and the bezel. Figure 1-2. 2600 Game Console 2600/2600A Domestic VCS ...

RF modulator (See Figure 1-3). 0 PLAYER OPTION SWITCHES Switches SlOL thru SL04 are double-pole, single-throw. Switches SL05 and 5106 are double-pole, double-throw. All switches are connected between the switchboard and the motherboard by 1 2-conductor flexible ribbon cable. POWER SUPPLY The power supply is composed of a +5 voltage regulator, filter capacitors, ...

combination Random Access Memory - Input/Output (RAM-110) chip, and a Television Interface Adaptor (TIA) chip (see Figure 1-3). The board also contains numerous capacirors, resistors, transistors, and other assorted electronic components. These parts are all listed in Section 8, PARTS LIST. a MICROPROCESSOR CHIP The heart of the VCS is the 6507 microprocessor ch ...

The major difference between the newer single board VCS (2600A) and the original VCS (2600) is that all of the components formerly on the switchboard are now located on the motherboard (See Figure 1-5). This includes the player control function switches (Power ON/OFF, COLOR/BW, GAME SELECT and GAME RESET), RF modulator and power supply circuitry. The single board design eliminates the need for the ribbon cable, which ...

In addition to the component changes, the physical location of several parts has also been changed. Instead of having the right and left difficulty switches placed on top of the game, they are located at the rear of the console next to the game controller plugs. The channel selector switch is also located at the rear of the console. The game cartridge socket is no longer angled, but is mounted vertically on the bo ...

cartridges, the game console, and player controllers. The 2600 switchboard and motherboard assemblies are housed within an outer casting and a r e the principle assemblies addressed in the remainder of this manual. The boards are connected by a 12-conductor ribbon cable which passes not only power, but also data between the two boards. Three chips of the notherboard ...

On the following pages are representative silkscreens and switchboard schematics for the ATARI Video Computer System. The motherboard schematics for all 2600/2600A VCS models are located in the pocket at the front of this binder. Minor variations in design may be encountered depending on the production date of the game, but these schematics provide all details required for an in-depth understanding of all 2600 units, in ...
