In a nutshell:

• Write text in AppleWorks 5 on my Apple IIe
• Save to a virtual drive via ADTPro over serial port
• AppleCommander can read the ProDOS virtual drive image file
• AppleCommander can also extract AppleWorks word processor files and convert to text / RTF / HTML

Gluing it all together: A script running on the Raspberry Pi on where I run ADTPro could auto-extract new word processor files as text via AppleCommander and publish them somewhere on the web as a blog-like thing.
