Version 0.6
AVR Keyboard Toy v0.6
This version implements a line editing experience to replace the serial input implementation (much like BASIC editing on the C-64). Cursor keys can be used on the PS/2 keyboard to move the cursor, or, for debug purposes, a serial device can be connected to UART at 9600 baud, and the cursor can be manipulated via Ctrl-W, Ctrl-A, Ctrl-S, Ctrl-D.
The hardware has also been changed in this release, opting for the TQFP package instead of the PDIP ATMega328p, removing the port expander which I couldn't find a way to incorporate well, and moving the piezo speaker to PB1 (digital pin 9). The whole design, minus the headers and optional resonator, is now surface mount also.
