Card sorting by slot type
Pick up each card and using the following chart, put each card in one of five piles (PCI, PCIe, ISA, AGP and miscellaneous.)
Connectors are circled in the images below. They are typically gold and also known as teeth or fingers.
Connectors are either rectangular (circled in red in the image above), or interlocking (circled in green the image below).
A card's connectors are usually all the same size. An exception to this can be viewed in the image below. Smaller connectors are circled in blue and larger connectors are circled in red.
