[comp.periphs] NuBus Spec Needed

bdale@hpcsd02.HP.COM (Bdale Garbee) (06/17/88)

Can anyone point me to a source for the NuBus specification?  I understand it
is IEEE-1196, and that it is used in the Mac II.  I'd like to evaluate the bus
for possible use in a workstation design...

Thanks.

	Regarding your query about the NuBus,  I suggest you buy a copy
of apple's "Designing Cards and Drivers for Macintosh II and MacIntosh SE".
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
