Card Connector Types

Step One -- Familiarize Yourself with Connectors

First, get a box of cards to be sorted, pour them into a pile in the center of the table, and rummage through them, looking for these connector types:

HD15 (three rows of holes) RJ11 (like for a phone) RJ45 (bigger than an RJ11) BNC (sticks out, like for cable TV) Little Round Sound Ports

There will be other connector types, but the above ones are all you need to pay attention to in order to complete this job.
