This is the third kit in a set of four kits. In this kit, you'll build the 8-bit computer's RAM module and program counter.

You should have already built the modules from the first two kit before starting this kit. This kit does not include a power supply and only two more spools of jumper wire since you will continue to use the ones included in the first two kits. Otherwise, you will need to provide a 5-volt power supply and perhaps some additional jumper wire of your own.
