Different card cages in the two machines. A soldered one on the 2400/3400/3500, with the TI PCI chip soldered on the underside of the main PCB. Pin-through-hole. A plug-in one on the Wallstreet, with the TI PCI chip soldered on the plug-in carrier of the card cage. Surface mount from the cage to the carrier. No brand or catalog number on the 2400/3400/3500 cage, otherwise it might be possible to identify a substitute which was Cardbus compliant. (But, "fine line" desoldering and soldering techniques would be required ... no easy skill to master). The difference are: 1) absence of two "keys", one per slot, and 2) presence of two shields, one per slot. But it might be possible that only the upper slot was provided with a shield on the Wallstreet. (Early Cardbus cards did not have the contacts required for the shield, anyway). The modification consists of removing the two "keys". I designed a special tool which could shave off the keys without having to disassemble the machine. But I have so little work which requires the modification, that, for me, it is less costly to disassemble the machines, rather than to invest the not insignificant machine shop time to make the special tool. (Of course, once the tool was made, any number of machines could be modified in about 20 seconds apiece). I have one 3500 and two 3400s which I have modified. The IBM Firewire card works fine, as does a no-name (VIA chipset) USB card. The "combo" (Firewire + USB; also VIA chipset) cards won't work on any if these, nor in the Wallstreet, either. Both the early (2400/3400/3500) and late (Wallstreet, et. al.) machines use the same obsolete TI PCI "bridge" chip, and it is possible that there are some incompatibilities between late Cardbus cards, and the machine's "bridge" chip. -- PowerBooks is sponsored by <http://lowendmac.com/> and...
