Yup, I realized that after I opened them both up. It still worked out fine, though. The RAM card in the 280 was a 36mb and the one in the 2300 was a 14mb, so I just swapped them, and both seem to be working just fine, and now we have enough built-in memory on the 2300 to run Ferazel's Wand and a bunch of emulated Gameboy games (among other things) on our long drive to Florida tomorrow! Plus, I was finally able to get our digital camera to connect to it through the serial port, so now I can easily off-load the images to the 500mb partition I set up on the HD, eliminating the necessity for me to go buy a bigger CompactFlash card. I love these little Macs -- too bad I can't find any decent batteries for it without spending a fortune! (I hollowed one of them out to use as a light-weight "filler" for the battery compartment, since all of the dead ones I have cause it to shut down when inserted.) Thanks!
