I have one here for repair at the moment and although it won't start, there;'s no sign of a wireless switch or a Function key with the wireless icon on it so it seems it predates wireless technology. All is not lost, though - you can buy a USB wireless adapter, sometimes called a dongle, very cheaply and that will do the job.
how do i make a ibm thinkpad 600 e be about to connect though a wireless connecton
What did you figure out, I dusted off my Thinkpad and am hoping to upgrade it to play a little, error messages for sure, but this could be a project!
does this TP 600 have wireless?
how can we upgrade to ethernet?
