Dad's Custom Atari Peripherals – By Jim Trageser

This piece chronicles the inventive spirit of an electrical engineer dad who, with a background in designing early air-collision avoidance systems, brought his technical prowess home to enhance his children's gaming experience on the Atari 400. It's a nostalgic look at a time when hardware modification was a personal endeavor, driven by necessity and curiosity.

• The author's father, an electrical engineer, began by building a CMOS KIM-I kit computer from a blueprint, later adding an RF output and serial port.
• After acquiring a Fairchild Channel F and then an Atari 400, the family faced the notorious 'joystick killer' challenge of the game 'Decathlon'.
• In response, the dad sourced an industrial, single-axis, two-directional joystick from a surplus shop, built a case, and wired it to an Atari plug, making 'Decathlon' playable without blisters.
• Other modifications included rewiring a mercury-tube-based industrial controller (though impractical for gaming) and adapting fragile Fairchild joysticks for the Atari.
• Perhaps his most impressive feat was connecting a surplus Atari 800 keyboard to the Atari 400 by building a custom case and adding a Centronix 24-pin parallel cable.
• Many of these bespoke peripherals are now part of the Computer Museum of America's collection, reflecting a unique chapter in personal computing history.

The story is a charming testament to a bygone era of hands-on electronics, where limitations sparked creativity and a father's engineering skills provided unique solutions for his family's digital entertainment and education.
