Three great projects on GitHub to update your Apple II computer! I sell these printed circuit boards separately in my eBay store but you can buy all three to save money. The VGA project is very popular. The RPI board allows you to use a Raspberry PI Zero 2W in your Apple for it's networking and storage. You can use disk images such as Total Replay with it. With the game pad pcb you can build a NES style game pad for your Apple II. Below I've listed the GitHub links as well as a YouTube video showing the RPI board in action.
