Here’s a fun one, I was trying to make sure the resistor based trick to shift from 5 to 3.3V worked but because my current generator is another Pico (that works at 3.3V) I’m using an HCT chip to bring it up to 5V. It works for both v-synch and h-synch but the chip can’t switch fast enough for passing the video signal properly, so the background checkerboard pattern turns to solid black! And you can see the slight delay it adds, as the image is shifted right a pixel or two. #RetroApple
