This is true.  NuBus can, in theory, support lots of memory.  It's a little
wackier than Zorro bus, though.  As I recall, each card gets a primary chunk 
of 16MB, and an optional second chunk of 256MB.  NuBus supports a maximum of 
16 such cards.  If you have an 8 slot Mac II, you should be able to add in
8*256, or 2GB, of contiguous memory.  Of course, Macs have only had a real
use for more than 16MB of RAM since the 15th of May, when they got 32 bit
addressing in the OS.  Also, the NuBus is pretty slow, and it can't support
68030 burst cycles.  So it's less than ideal for memory expansions, but it
can support them.  Apple does plan an enhanced NuBus, based on the NuBus 90
speedup hack that NeXT apparently generated for their 12.5MHz NuBus-ish
expansion bus.
