Hi,

I'm trying to ID some unmarked Mini DIN-4 cables (ADB vs S-Video vs ??) from a mixed parts box - and don't have an Apple brand cable to compare with.

Using a cheap old continuity tester, looks like two types (for both pins seem wired straight through)

1) The cylindrical shells on each end are connected through the cable

2) The cylindrical shells on each end are isolated from one another

Also found a couple of web references which say either ADB and not S-Video - OR - S-Video and not ADB - connect the shell with the ground pin - which I didn't find for any of the cables.

Thanks.
