Inside the Big Trak Toy

David Cook from the Robot Room has Reverse-Engineered the PCB for the Big Trak Toy. This is a toy that was built in the late 70s. It is interesting to see how things worked 25 years ago!

“The motherboard is single layer/single sided. There are between 8 and 10 jumper wires acting as second-side traces on the component side. The PCB does not include a silkscreen (printed layer), so the component numbers are not listed anywhere. As such, the part numbering referred to on the page is mine, arbitrarily based on which IC pin the parts are connected to.”

What is a Big Trak Toy and whats the point of reverse-engineering it?

Hi Aaron,

It is usually done so that the unit can be controlled by something non stock such as a new microcontroller that gives it more features.
