I am looking for opinions on what people feel are the better SD card and/or USB drive storage solutions for Apple II, II+, IIe. I found the CFFA3000 online but it looks like that is out of production for now. (If schematic is open source I would love to have a copy as I have several empty proto-boards).
I am more looking for DIY versions vs off the shelf.
Any input of your opinion or experiences is most welcome.
