I ordered five DPDT relay switches early last week from Newark. They have not arrived yet. I have not prototyped a digital/analog circuit is over thirty years. We used wire wrap in the day. Yesterday I bought from Radio Shack solder, a low power iron, some small tools, and three different kinds of proto boards. It is not obvious how we physically attach capacitors, resistors, transistors, to these boards. I gather the inline chips get plugged into sockets that have pins which fit into these proto boards. Their back sides are designed for some kind of wire attachment. Wire wrap?

Can you guys point me to some revealing photographs?
