Maybe this is a lost cause?
Jonas, The problem is, they are not the same connector. The webcam you have uses a DB-25 parallel port (IEEE 1284) for data communication along with an AT port for power. (AT and PS/2 can be converted with a simple passive converter, due to the standards being identical, electrically. Also, DB-25 is found on some older Macs, but for the external SCSI interface, not IEEE 1284) IIRC, neither will work on a Macintosh, without some serious work. Also, the round connectors, though they look similar, are quite different in implementation. ADB is completely incompatible with PS/2, although the plugs look similar, and if you try, the PS/2 keyboard won't plug into the ADB port. (ADB uses a mini-DIN-4, as opposed to a mini-DIN-6 connector, with a differently positioned and shaped square pin to position the connector) If the webcam was designed for a Mac, at that time, it should have had a round mini DIN-8 connector for data communications (RS-422) and then I'd think it would draw power from the ADB bus.
