Homebrew love for the Indy 500 controller?


S1500

As far as I can google, there was only 1 game made for the 2600's Indy 500 controller. Were there more?

 

I mean c'mon, full 360 degree rotation! Sure, only 1 controller per port, but still.

 

One would think there would be the finished "radial pong" game, or a radial breakout. Or a better Indy 500 game with more depth & better graphics.

 

Hmm.

What is really different internally that makes not just a paddle? Why did they have you buy paddles AND the driving controller.

Three main differences:

1. Paddles have to be constantly checked inside the kernel, therefore further limiting the display capabilities

2. DC allow unlimited turning, while paddles are limited left and right

3. Paddles have a much higher resolution

Yes. Something like every rotation changes a value on a counter and the games use that value to determine rotation... have to pull out the field service manual to double check... where as a paddle is a varriable resistor that changes the charge going to a capacitor inside the atari that the TIA chip times to determine position. Oddly the paddle line is the only controler port line NOT going to the 6507/RIOT combo.

A paddle is a potentiometer. It's an analog device.

 

A driving controller is a gray code device. It's digital.

While they look the same, the functionality is different - just like how analog and digital joysticks look similar but give you different control capabilities.
