>>Was it the bandwidth, or the fact that Nubus mobos are so different from PCI >>mobos?

You would need a CardBus controller designed to operate on the NuBus architecture, and no one created such an animal. Doing so wasn't cost-effective because by the time CardBus came into vogue, Apple had already embraced PCI in the 2400 and 3400. The only possible application for a NuBus CardBus controller chip would have been in the 1400. It could have been done, since the NuBus is actually a 32-bit bus (the first 32-bit expansion bus ever used, in fact), but by 1996, the NuBus was on its way out. There's no such thing as a 16-bit CardBus card, that is impossible. CardBus is a 32-bit protocol all the way. 16-bit PCMCIA cards are just 16-bit PCMCIA cards, never CardBus, although CardBus controllers are backward-compatible with them. >>I believe the concessus (on the website I found) was that the 1400 should be >>able to support a CD-R, and even a DVD-R, like with my drive. >>1st of all, I do not even know if the DVD card (from Wallstreets and >>Lombards) will work in the 1400. It is cardbus or PCMCIA? WallStreet and Lombard DVD cards are CardBus and will not work in a 1400. I'm not even sure they work in a Kanga hacked for CardBus support. >>Secondly, I read about a mod that worked w/ a DVD drive in a 1400, but the >>picture when showing a movie was s-l-o-w and jerky... BUT the user only had a >>183mhz PPC upgraded 1400. I have a 400mhz processor... A G3-400 should be able to play the DVD in a 1400 if you can get it working, but I would be willing to bet it won't be perfect. Between the RAM limitation, the 32-bit memory bus and the 33 MHz processor bus, you have a lot of bottlenecks there and all of them will show up in DVD playback. That's why even the 466 MHz G3 for the 1400 can't stay with a much slower Lombard most of the time. -- PowerBooks is sponsored by <http://lowendmac.com/> and...
