Atari 5200:Connector Pinouts

Cartridge Port
Note: Pins 1 through 18 are at the front and numbered from left to right. Pins 19 through 36 are at the back and numbered from right to left.

Pins 9 and 10 provide access to memory ranges $8000 to $BFFF and $4000 to $7FFF, respectively. Pins 18 and 36 act as a cartridge interlock to prevent the console from applying power to a cartridge which is not properly connected. When these two pins are shorted together, they provide 5V to the cartridge and allow the 5200 to boot.

Controller Port
Note: Female is connector at the console. Male is connector at the controller. Diagram pictured is of the connector at the controller end.



Expansion Port
Note: Pins 1 through 18 are at the top and numbered from left to right. Pins 19 through 36 are at the bottom and numbered from right to left.
