My g3 ibook died and I picked up a TiBook (M8859LL/A).  When I added 
memory to the ibook I think i go a 512 card that was faster than I 
needed (133 MHz) and I think I can put it in my TiBook, which has (2) 
256 cards.  Just wanted to make sure that giving it a try won't blow up 
anything if it doesn't work.

That TiBook is the final generation (November 2002 to September 2003),
which takes PC133 SODIMMs. You can mix capacities. I had 768 MB in my
TiBook (one generation earlier).

As long as your iBook memory is a PC133 SODIMM it will work fine.

Just follow the usual precautions: shut down the computer, remove the
battery, unplug the power connector (and everything else external), and
try to do it in a static-free environment (e.g. touch an earthed metal
object to discharge yourself before touching the memory or anything
inside the TiBook).

Thanks.  Something I forgot to ask - if all goes well and I decide to 
replace the other 256 card with a 512 do I have to worry about a 
manufacture match? I know I need at least PC 133 but if I get something 
that exceeds specs would that be a problem?

And while I remember (I think I might need a memory upgrade myself) 
would it matter which slot the 512 goes in (with the 256 & 512 
configuration)?

Should be fine. It helps for the first one that you have already been
using it in a Mac, because it is known to be compatible.

Another PC133 SODIMM might not be known to be Mac compatible, but as
long as it works in any Mac, it will be fine with a different branded
one in your TiBook. You might not get a speed benefit if one has fewer
wait states than the other.

Some memory modules don't work in Macs, and the problem is often that
the "serial presence detect" EEPROM on the module has not been
programmed, or is missing information. The memory module might work in
PCs which rely on BIOS settings to configure the memory layout and
speed, but the Mac depends on getting information about the module from
that EEPROM, otherwise it completely ignores the module. You can also
have problems if it hasn't been programmed correctly.

That doesn't matter. The memory controller is smart enough to figure it
out.
