6502 Wozmon PCB
The upper left corner of the PCB has ports for +5V (barrel connector) and an RS-232 nine-pin serial cable. PWR and CLK LED's will illuminate when power and a clock signal (from the onboard 1MHz clock) are present, respectively. The PCB can be reset via the RESET button directly below the RS-232 port. The RESET LED will illuminate when the RESET button is pressed.
