It has overviews of the Mac-NuBus combined architectures as well as signal, timing, features, definitions, arbitration, and NuBus Card electrical Design guide (separate chapters on electrical and physical, and firmware). And then more on the device drivers from the Mac and even a few design examples. The latter include hardware and software examples. Volume V of Inside MacIntosh might be helpful as well. However, these books (there is a set of 5) besides the "Designing Cards ...MacInntosh SE" book aren't free. At Fry's they discount them and the price is still $17 - $20 apiece. The good news is that they are - at least I think so, so far- fairly well written. Have fun Jeff
