What input devices used the paddle, i.e. POT inputs?


Recommended Posts

Quiz - What input devices used the paddle, i.e. POT inputs on the Atari or C64? Below is a list I have compiled with help from folks on Twitter.
 
This question came to mind after I spent a lot of time to characterize the input_resistance/byte_value curve of the A2D converter on the C64 SID (which is nonlinear, spoiler alert, and I suspect the POKEY POT inputs are equally nonlinear).
 
The exact response curve does not matter for paddles or mice as you are moving them in proportion to what you see on the screen. For a security dongle or the 'The Party Quiz Game' controllers it might make more a difference as they expect a certain resistance to result in a narrow range of readings from the SID.
 
Input devices that use POT input:
• Paddles
• The Party Quiz Game 4-button controllers
• Atari CX85 keypad (POT Y used as digital input)
o Cardco Cardkey Numeric Keypad clone of above
• Atari Video Touchpad (Atari 2600 for Star Raiders), can use on C64, etc.
• Commodore 1351 Mouse
• Koala Pad
• Mssiah (uses external pots for controls)
• Vaisala HAWS weather station
• Security dongles

I was curious about trackballs, but apparently all (?) of them use pulsating digital signals to simulate analog movement instead of the pots, so oddly those don't belong on the list.

 

Since you list touchpads, I suppose the Kid's Computer Keyboard from Muppet Learning Keys belongs too, as I seem to recall it was Koala compatible in some way. But I can't tell for sure it is.

I just learned from someone on Facebook that the Atari CX80 track ball can use analog (mouse) or joystick (digital) modes. The Muppet keyboard in a new one though. I wonder if it was released for other systems as well?

The Muppet one supposedly was supported on the C64, Apple II series (though different connection, I suppose) and possibly Atari 8-bit, at least electronically. It was developed by Christopher Cerf and Bill Prady with (at?) Koala Technologies and Sunburst Software.
