The Main Board -- Unpopulated
Header strip for the front panel along the top. The upper two sockets are for the 74HC165 switch controllers, the socket for the single 74HC595 controlling 8 LEDs is below that. A header strip for the DS1307 RTC with the ATMega socket next to it. The 'T' header strip is against it is for the power supply and crystal. Crazy point-to-point wiring (with a sadly limited palette of colours) in between.
