" A Bondi iMac *officially* maxes out at 256MB, but can be pushed to
" (iirc) 384MB if you have the correct-architecture modules in the correct
" slots.  But it'll only work one way around.

the place we got her imac sticks from had low-profile 256M sodimms for
the bondi they said would work in either slot.  i noticed that b/c i
have a bondi, 333MHz.  as it happens, it already has 128s or i'd be
really tempted.  maybe if/when i ever get a chance to try putting 10.4
onto it...  but i'll need a bigger hd too.  i want to slice it for
both 10.3 and 10.4 roots, as well as /users.

likewise the slot-loader imacs officially max at 512M but they have
512M sticks that push them to 1G.

as i understand it - and as alluded to in the initial u5/u10 posts -
sticks of supported capacity can have more than one organization,
with a variable number of address rows and cols, but at least on macs
larger modules of max rows * max cols work.  i'd guess the u5/u10 work
the same; maybe all machines using generic mem ctlr chips do too.
