atarilux Posted May 25, 2021 Share Posted May 25, 2021 (edited) Hello, I started out doing some electronics tutorials with a Raspberry PI, and now I am trying to do so on the Atari 800XL. So far I have had some success using the joystick port, but I was wondering if anyone can recommend some good online tutorials or info? So far I figured something out via Mapping on the Atari.. but need a little more. A while ago I came across some materials, but either the site has gone or my Google search terms are not quite accurate enough.

TGB1718 Posted May 25, 2021 Share Posted May 25, 2021 One thing to remember, the Raspberry Pi GPIO pins are 3.3V, everything in the Atari 8 Bit's is 5V. I built an EPROM Programmer and use 2 way level shifters between the different voltage levels. Quote Link to comment Share on other sites More sharing options...
atarilux Posted May 25, 2021 Author Share Posted May 25, 2021 Thanks, yes I noticed this already, so a few resistors were put in reduce the voltage. Quote Link to comment Share on other sites More sharing options...
