## Purpose ## 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. Initially this is storage via virtual ProDOS compatible drive. There is also support for executing Linux commands from the Apple II via a rudimentary console. Next might be adding virtual serial card support over wifi. Future enhancements could 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. 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 includes using attached RPi Zero W for it's storage, network and processor to provide new functionality for the Apple II.
## Project Status ## Project Status
This is an early stage project. Currently four prototype revisions have been assembled and tested. It is now possible for the Apple II to boot from and write to a virutal hard drive image stored on the RPi in any slot and execute simple commands on the RPi via an Apple II application. The code has no error handling or tests yet and is incomplete. So far, this is a project and not a finished product. The current prototype is on the fourth revision and a few have been assembled and tested. It is now possible for the Apple II to boot from and write to a virutal hard drive image stored on the RPi in any slot and execute simple commands on the RPi via the Apple II.

## Roadmap ## Roadmap
1. DONE - Build initial prototype that reads/writes virtual hard drive 1. Wifi setup tool
2. DONE - Create firmware to make the card a bootable device 2. Help in command line
3. DONE - Fix board with updated second prototype PCB 3. Software on default image to get firmware updates
4. DONE - Add ProDOS clock support 4. Proper ProDOS clock driver (currently just directly sets values on block reads)
5. DONE - Add simple RPi command execution (does not keep context between commands yet) 5. Support for direct file read/write without drive image
6. DONE - Create new schematic/PCB with faster data transfera 6. Image conversion on download
7. DONE - Add hardware support for in-system firmware updates 7. Web service call support
8. DONE - Add multi-page firmware support 8. Full terminal emulation
9. DONE - Add boot menu 9. Remote code execution
10. DONE - Add RPi command in firmware 10. Proxy VNC connection, rendering as Apple II compatible graphics
11. Add firmware update software
12. Add proper ProDOS clock driver (currently just directly sets values on block reads)
13. Add directory context to RPi command execution
14. Add full terminal emulation
15. Add support for direct file read/write without drive image
16. Add web service call support
17. Proxy VNC connection, rendering as Apple II compatible graphics
## Setup ## Setup
