Currently one partially completed physical prototype exists that sends data unidirectional from the Raspberry Pi Zero W to the Apple II via 8 bit parallel data bus. The schematics are incomplete but now include bidirectional communications. There is no firmware or PCB design yet, nor code for the RPi. ## Purpose -The purpose of this project is to provide I/O for an Apple II series 8 bit computer via a Raspberry Pi Zero W which is powered by the Apple II expansion bus. +The purpose of this project is to provide I/O for an Apple II series 8 bit computer via a Raspberry Pi Zero W which is powered by the Apple II expansion bus. This could be expanded to use the RPi for more complex processing as per request from the Apple II. For example, the Apple II could request a web page or application and the RPi could calculate this in Apple II hi-res graphics mode and send the image data back to the II for display purposes. ## Similar Project If you're looking for complete hardware design or prefer having Apple II peripherals control a control a Raspberry Pi rather than simply using the Raspberry Pi to provide storage and network access to the Apple II, have a look at David Schmenk's excellent [Apple2Pi](https://github.com/dschmenk/apple2pi) project.
