ZX81_-_Composite.jpg
Here is a very simple ZX81 modification to replace the ugly modulated video output by a composite video signal.

I tried several modications from the WEB, but due to special video standard in france, none of them was successful on the ZX81.
So, here is my own adaptation. If it works for me, it should work for you !
The attached file contains the schematics and some pictures.
Have fun !
