TTYpewriter!

Converting electronic typewriters to terminals

Current Hardware in use:

Arduino Mega R3 + Wifi.
- ATMega2560: handles the interfacing to the typewriter, should act as a dumb terminal in it's own right.
- ESP8266: bridges our dumb terminal to an external webserver.
Canon Typestar 7 Typewriter
- This can be any digital typewriter - I chose this because it was cheap, but there's a lot of information about it online thanks to Alex Dueppen

Stage One: Keyboard
- Read and interpret keystrokes from typewriter keyboard, print to serial
- Implement function keys ('code', 'backspace', 'left'/'right', etc.)
Stage Two: Dumb Terminal
- Set up basic terminal on mega
- Detect Keyboard scan pulses and set corresponding rows/cols high to simulate keystrokes
- add ability to switch between typewriter (passthrough) and terminal (only print RX/echo) modes
Stage Three: TTY
- Set up client for protocol of choice (TBD, possibly Telnet or SSH) on ESP8266.
Other Goals:
- Expand Keyboard maps to provide compatibility for more typewriters
