PC Keyboard interface / tester

Hello, I'm George Hotz. Here is my keyboard-lcd interface. (Yes, it works
for me)

Thank you for hosting these contests.

Reads PC keyboards and displays Scan code or decoded ASCII to an LCD.

The connections are as follows:

RA.0 = Clock of keyboard

RA.1 = Data of keyboard

RA.2 = lcd_RW

RA.3 = lcd_e

RB.4 - RB.7 = Pins 4-7 of the LCD, respectivly

RB.0 = lcd_RS

It uses the SX Key/Blitz to program it, and runs using the internal 4mhz oscillator
