I recently picked up a PowerBook 2400C that was upgraded to a G3/400mhz + 80mb of RAM, but was originally a (I believe) US 180mhz model. During my readings I remember hearing about modifying the 2400C to support cardbus cards, which involved cutting two wires on the board.
I went for it, removed the wires fully, and tried to use a OrangeLink Cardbus FireWire card, which didn’t work. The card would show up as a FireWire card in the OS (OS9 helper + Mac OS 9.2.2 + Old World FireWire Patch) but a Gen 1 iPod would not connect to it, only charging (because the card was hooked to power from the wall). However, when the iPod was plugged in, it did enter Disk Mode and also the PowerBook cursor seemed to “lag.”
I’ve heard that apparently while US/JP 180mhz units didn’t fully support cardbus, the newer JP 240mhz did fully support Cardbus. I’m currently working to obtain one of those, but I’m just curious…
Has anyone had experience with adding FireWire to the 2400C and getting it actually working?
