What I see on the board:
Connector for serial communication with IC max232 and sone capacitors.
A crystal with two capacitors. This is the clock for the 8051.
Power through a jack or the USB connector
A programmer connector.
And on the other side of the board, a row pin headers, leds, switches, potentiometer. Perhaps you can connect the pins of the row to the leds etc on this board.
