So I'm trying to do this:
Output composite video from the Arduino into the internal power connector of the Macintosh Classic 2.
I've found the schematics of the power connector: http://pinouts.ru/Power/macclassicpower_pinout.shtml
And I've found the technical manual for the Classic 2: http://members.optusnet.com.au/eviltim/macmp3/Mac_Classic_II.pdf
I've found this great schematic on hooking up the Arduino to output composite: http://pinouts.ru/Power/macclassicpower_pinout.shtml
Now I'm trying to figure out how to put everything together. I'm going to use the code from the Arduino Pong example (http://dailyduino.com/wp-content/uploads/2008/11/daily_duino_composite_video.txt) and refit it to output 512px x 384px for the CRT screen.
So my questions are:
I guess the signal pin of the composite goes on pin 6 (vidout) of the Macintosh classic. Where does the ground/return of the composite go?
Do I need to change the update rate from the Arduino Pong code to use it with the CRT monitor from the Classic 2?
Any help is appreciated.
