From Oliver Schmidt:
A2Pico is a generic Apple II peripheral card based on the Raspberry Pi Pico. As of today there are already five different A2Pico firmwares available basically turning A2Pico into five different cards:
- A ProDOS HDD emulation with access to the image files from your PC via USB
- A softSP card emulation that makes your Disk II card work as a SmartPort card
- An Appli-Card emulation that allows to run CP/M programs on your Apple II
- An Apple2-IO-RPi variant that allows to connect the Linux RPi via USB
- An Apple II Pi variant that allows to connect the Linux RPi via USB
- …and there are for sure more firmwares to come soon.
Some background: Soon after the introduction of the Raspberry Pi Pico in 2021 Glenn and I started to experiment with directly connecting it to the Apple II slot bus. In 2022 I published a working Pico firmware on GitHub. Based on that we started to implement a prototype which I presented at KanasFest 2023. Considering the next steps I decided that my firmware should be accessible to the DIY community so I teamed up with Ralle to modify both hardware and firmware in order to allow for a simple through-hole design beside the SMD design.
