Thanks for catching that. It turns out that the manual I found is
worthless: the manual was for my computer model, but the actual
motherboard inside is a different one than what is described in the
manual. (...sigh...)

Tried again, this time just comparing against the specs of the RAM
actually in it. I believe that this would work:

http://www.memorydepot.com/details.asp?id=DR2533NU004%2F1GB%2FK

That's DDR2 533Mhz PC2-4200 240PIN. I would like to get the EEC version
of that:

http://www.memorydepot.com/details.asp?id=DR2533ER004%2F1GB%2FL

However, the RAM currently working in the computer is not EEC, so I
haven't the slightest clue whether or not that would work.
