Description

This is a new RGB (SCART) card for the venerable Apple 2c computers.

 

It connects to the dB19 video port at the back of the computer.

 

The RGB decoding part is using only standard logic components as it woudl have been done 40 years ago.

This make this design simple and very easy to build without any special tools to program complex devices.

 

My philosophy is also to avoid putting devices having 100 or 1000x the horsepower of the original computer to provide improvements.
