Cool project! Do you have any plans to make these cards available to hobbyists when you have the drivers worked out?
I've always thought it would be amazing if somebody developed an ethernet interface for the 100-series powerbooks. It would certainly make it easier to transfer files to and from my trusty Powerbook 180.
Yeah, the plan is to open-source everything including PCB designs, drivers and CPLD firmware.
I'm not sure if it would be possible to redesign the card to fit in a Powerbook 100-series though. The Powerbook 180 appears to have a modem expansion slot but that doesn't give access to the processor bus AFAICS.
