I've uploaded a new pic(still blurry thanks to a cheap digital camera), showing it with all the connectors attached. Missing from the second pic, the joystick is shown connected as are the autofire switches. The 24 pin chip is a "Microchip" (brand) PIC16C57-XT/P
the second line on the chip chip is: 9731CAM
