NuBus-based PBs use one bridge chip, a NuBus-to-PCMCIA bridge chip; PCI-based PBs use another bridge chip, a PCI-to-Cardbus bridge chip. TI definitely made the second. Although NuBus was a TI development, used by Apple under license, I don't believe TI made that NuBus-to-PCMCIA bridge chip. The former supports 16 bit transfers only, and is PCMCIA compliant. The latter supports 32 bit (and is backward compliant for 16 bit transfers), and is Cardbus compliant (as well as being backward compliant with PCMCIA). All USB and Firewire cards are Cardbus cards, and will not operate in a PCMCIA slot. Not just because of the card key which prevents their insertion onto a PCMCIA cage, but because of the additional control and data lines which such cards depend upon. >In short it won't work becuase the PCMCIA controller is not compatible >with new-age High Speed CardBus cards, which include (to the best of my >knowledge) all USB, USB 2.0, FireWire and 100Mbit ethernet adapters, as >well as others I have likely missed. There are 10/100 ethernet cards which were 16 bit, and hence were PCMCIA, but no Mac drivers were ever released for these cards. All USB 1.1 cards, were Cardbus from the git go. USB 2.0, too. Firewire, too. Only a very few 10/100 ethernet cards were PCMCIA, and these were soon dropped in favor of 10/100 Cardbus cards. There were a few Cardbus cards which did not include the copper grounding strip usually found on Cardbus cards, but these cards were still keyed as Cardbus cards. 3Com made an "X-Jack" 802.11b WiFi card which appeared to be a PCMCIA card because of the absence of the copper grounding strip, but it was really a Cardbus card, and it was keyed as such. It was also 3Com which made the 10/100 ethernet cards which were PCMCIA, but had no Mac driver available. -- PowerBooks is sponsored by <http://lowendmac.com/> and...
