Using a modern USB joystick on a vintage computer (Atari compatible)

[dwight]

You can get a USB master shield for the Arduino

cheaply enough. You can then use the Arduino's

PWM output and analog input to translate joystick

to DC voltage.

One would need to put a lowpass filter on the PWM

output. Another option would be to use a multiplying

D/A instead for the output. I don't recall the output

frequency of the PWM but the response time of

the filter might limit the use of PWM for translating

joystick operation.

Subject: Using a modern USB joystick on a vintage computer (Atari compatible)

I've seen plenty of examples of adapters to use a vintage joystick with
a modern computer.

I'd like the opposite - to use a USB controller with a vintage computer
(Atari compatible - for example ZX Spectrum, Commodore 64). Does anyone
know of an adapter or a homebrew project?

Thanks, Mark.
