Exactly, and another reason to connect the RPI to the Apple. The Apple II bus is so much easier to play around with. it seems the RPi GPIO pins are really meant to connect with other low-voltage devices that are very power sensitive. It takes a little bit of extra care and hardware to play with any real-world devices without damaging the RPi. The Apple II, on the other hand, is almost bulletproof. That is where I want to use the Apple II as a retro-Arduiono for hardware experimentation, but use code running on the RPi. Time sensitive operations, like reading/writing disk sectors, can be implemented as a downloadable routine to the Apple II and executed locally.
