How to connect to the internet with my 3com palmIII?

Answer 1

There is an Internet Kit that would work for your Palm:

You may also want to update any software upgrades directly from Palm, as follows:

I would recommend that you upgrade to a newer, Web-enabled Palm, such as the Tungsten T/X, or the LifeDrive. Even the older Tungsten C, with built-in keyboard would be a delight over your Palm III. Good luck!
