thanks mr draven (can i call you nick/nik/nic/gnyq?)
meg = the angel i mentioned earlier
i found out the specs by removing the keyboard (use the two little slide switches at the top in-between the keys) and looking at the serial sticker above the airport card slot.
they are both 12" dual usb models (from around 2001) and the sticker says something like "600mhz/128mb/15gb/cd", which i guess means its a g3 600mhz processor with a 15 gig hdd, 128 meg of ram and a cd drive
of course, if you can turn them on and that, you can just click the apple on the menu bar and go to 'system info' then click the 'more info' button if you need more (this will launch the system profiler app that pen mentioned).
this wiki page lists all the ibook models with basic specs and release dates
if when i can turn them on it turn out that they only have a cd drive, i'll be replacing it with a dvd drive.
i only need to get one airport card though as one of them already had one in it!
right, i'm off to look for 10.3...
