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. 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.
## Project Status
This is an early stage project. Currently one board has 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. The code has no error handling or tests yet and is incomplete.
This is an early stage project. Currently three prototype revisions 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.
## Roadmap
1. DONE - Build initial prototype that reads/writes virtual hard drive
2. DONE - Create firmware to make the card a bootable device
3. DONE - Fix board with updated second prototype PCB
4. WORKING - Add ProDOS clock driver (real driver later, for now just directly sets values)
5. WORKING - Add RPi terminal access (does not keep context between commands yet)
6. Add web service call support
7. Proxy VNC connection, rendering as Apple II compatible graphics
8. Create new schematic/PCB with faster data transfer
4. DONE - Add ProDOS clock support
5. WORKING - Add simple RPi command execution (does not keep context between commands yet)
6. DONE - Create new schematic/PCB with faster data transfer
7. Add proper ProDOS clock driver (currently just directly sets values on block reads)
8. Add directory context to RPi command execution
9. Add full terminal emulation
10. Add support for direct file read/write without drive image
11. Add web service call support
12. Proxy VNC connection, rendering as Apple II compatible graphics
## Setup
1. Have PCBs made from the gerber and drill files in the Hardware folder

7. Put microSD card in the RPi
8. Install the expansion card into the Apple II
9. Power on the Apple II
10. Install Go on the RPi over ssh
10. Install Git and Go on the RPi over ssh
11. go build Driver.go
12. Copy a ProDOS hard drive image onto the RPi
13. ./Driver HARDDRIVE.hdv
14. Setup the Driver as a service or to autostart via cronjob
