Editing Atari XE Game System (section)

== Physical Design and Ports ==

The XEGS features a wedge-shaped grey console case distinct from the 65XE's computer-style housing. The top panel includes five pastel-coloured membrane buttons: '''Power''', '''Start''', '''Select''', '''Option''', and '''Reset'''.

=== Rear Ports ===

* '''Power input''' — Standard Atari XE/XL power connector (centre-positive 5 V DC)
* '''SIO (Serial I/O) port''' — 13-pin proprietary connector for disk drives, cassette, printers, and modems
* '''Composite video output''' — RCA jack
* '''RF output''' — RCA jack
* '''Channel select switch''' — Channel 2/3 for RF output
* '''Monitor audio output''' — RCA jack

=== Front/Side Ports ===

* '''Two DE-9 joystick ports''' — Compatible with Atari-standard digital joysticks, paddles, and the XG-1 light gun
* '''Cartridge slot''' — Top-loading, accepts all standard Atari 8-bit cartridges
* '''ECI (Enhanced Cartridge Interface)''' — Active active connector for enhanced peripherals

=== Keyboard ===

The XEGS detachable keyboard connects via a proprietary flat ribbon cable and connector on the right side of the console. When attached, the system boots to the Atari BASIC '''READY''' prompt (identical to the 65XE) and can run the full range of Atari 8-bit software including disk-based and cassette-based programs via SIO. Without the keyboard, the system boots directly into Missile Command or a cartridge game.
