Zapper Parts List

Please note that some of the part numbers may have changed. But the parts are all very basic so you will easily find another part that will work. According to readers' feedback, the 8 pin wire-wrapping socket is no longer available, you can just buy a larger one (e.g. 16 pin) and cut it to fit.

Hints for absolute novices:

Don't let unusual vocabulary deter you. A �lead� is just a piece of wire used to make connections. Label components as you remove them from the package. Practice using the microclips. If the metal ends are L-shaped bend them into a U with the long-nose pliers so they grab better. Chips and chip holders are very fragile. It is wise to purchase an extra of each in case you break the connections.
