Woo! For Retrochallenge 2013 I'm trying to build a VT100 Keyboard to USB Converter. Because of the strange serial protocol the keyboard uses, it's a lot more complex than you might imagine it would be.
Anyway, tonight I have my first proof that my clock generator and UART are working. Next step: reading serial data FROM the keyboard.
