Original Joystick adapter design from 2000

Original Joystick Adapter

In 2000, I designed a simple Atari numeric joystick to IBM PC analog joystick port adapter. This adapter was simply a voltage switcher that converted joystick movements to 0v, 2.5v, 5v (2.5v is centered stick). Easy you would say, but that was a bet I took with a friend that told me it was impossible to connect an Atari Joystick to a PC. This is where everything started… We are 16 years later and this quest for retro gaming is more present than ever!

As you can see, schematic was pretty simple…old_joy_schematic
