That Weird 7-Pin S-Video Port on Old Laptops

Even though laptops from around the early 2000s came with just about every conceivable port on them, they still would often feature a somewhat unusual combined video output port. While at its core this was just a 4-pin analog S-video output, the three additional pins on the mini-DIN connector provided some more features. Of course, as [VWestlife] found out during his archaeological research , not every manufacturer used the same pinout here.
