Here's my son playing the game. Click on any of these pictures for enlarged views.
Close-up of the board with most parts installed. Note the 7-pin sockets in the middle where the display goes. This is actually a 14-pin socket cut in half. It is MUCH cheaper than buying two 7-pin single row sockets!
Here's the same partially stuffed board on edge. This gives you a good idea of how high the transistors are mounted.
The kids' boards had blue and red sticky dots on both the PCB and chips. These were meant to help them both locate where to insert the chips and to orient them appropriately. This picture is from the PowerPoint presentation that walked the kids through the assembly.
There's no power switch on the game. To "turn it on" you must plug-in the power cable from the battery on the back! The kids often got the polarity wrong. It doesn't destroy the game when you get it backwards, though the voltage regulator will heat up and the battery will be sucked dry.
The game uses the PIC's internal oscillator without the capacitor that you would normally use. This allows the kids to slow the game down by touching R8. Quite often the kids accidentally touched a trace on the back of the PCB with the same effect. Some even learned to do this strategically when playing the game!
