There is a new book called :
"Designing Cards and Drivers for the Macintosh Family", 
Addison Wesley, 1990.

I would also recommend :

- "SN74ACT2440, NuBus Interface Controller", Datasheet from TI.

- "SN74BCT2420, NuBus Address/Data Tranceiver and Registers.", from TI.

- The Hypercard-stack "BoardID Registration Stack", which you can obtain
  from apple.com (130.43.2.2)

- "Debugging Declaration ROMs", Mark Baumwell, Develop Mag. Jan. 1990.

You will also need the MPW CRC-tool and perhaps a ROM emulator.
I have developed an interface card for NuBus using these references
(and some helpful advices from people at Usenet - thank you all ! ).
