I've got a friends office who needs to network PC and Mac's. I'm fine with the PC side of the coin, but having problems with the MAC side.

First off is the ethernet cards for the different Mac and I think buses. Any idea if I can just go with PCI cards for these computers?

They also have a Powerbook 1400CS any idea how to contect that?
