Keelog.com has a really concise description of how to build a PS/2 based keylogger. The main components are an AT89C2051 microcontroller and a 24C512 serial EEPROM. Once it is plugged in, the device begins recording all of the codes generated by the keyboard. The data can then be dumped using their keygrab software.
