The 3Com Ethernet driver looks very similar to the one from the 4.2 BSD distribution.

So I'll need to see if I can emulate how drivers are linked in and probed.
(We did both V7 and SIII ports to the Lisa)
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.
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.
I can probably help with drivers if you get stuck. (bearing in mind that it was 30 odd years ago)
I am looking for the Apple A/UX Device Driver Kit (APDA M8037/B), which should include a book titled “Building A/UX Device Drivers”. I am specifically interested in driver source code.
Here is an incomplete list of A/UX software and documentation of which I am aware. Helping preserve any of the missing items would be highly appreciated.
