## Project Status
So far, this is a project and not a finished product. The current prototype is on the fifth revision and about 20 have been assembled and tested. It is now possible for the Apple II to boot from and write to virtual hard drive images stored on the RPi in any slot (except slot 3), execute Linux commands from Applesoft BASIC and run a bash shell with VT100 emulation. The code has very few tests and is incomplete. Note that currently the firmware assumes an 80 column card is in slot 3 and than you have lowercase support. Most development has been done with an enhanced Apple //e with the card in slot 7. If you have other drive controllers earlier in the boot cycle, you can still boot from the Apple2-IO-RPi. For example, if the card was in slot 4, you could type `PR#4` from the BASIC prompt to boot the card. Note that the Raspberry Pi Zero W (and W 2) consume about 1/4 of all available power to the expansion slots when idle and close to all available power when busy. It is not recommended to have a lot of other cards in the system at the same time. If you have a problem or idea for enhancement, log an issue [here](https://github.com/tjboldt/Apple2-IO-RPi/issues). I recommend starring/watching the project for updates on GitHub. You are welcome to fork the project and submit pull requests which I will review.

## Similar Project
If you prefer having Apple II peripherals control a Raspberry Pi rather than simply using the Raspberry Pi to provide storage, network access and processing to the Apple II, have a look at David Schmenk's excellent [Apple2Pi](https://github.com/dschmenk/apple2pi) project. I am often asked about differences between these two projects. They are similar in some ways but essentially opposite. The Apple2Pi is meant for the primary machine to be the RPi, using the Apple II for it's peripherals. The Apple2-IO-RPi is meant to have the Apple II as the primary machine and just use the RPi for its processing, storage and network.
