The 2400c is basically the 3400c packed into a smaller case (with no internal CD-ROM drive), so anything that a 3400c can do, so can a 2400c. Even though my 3400c is running at 200 MHz with 80 MB of memory, that isn't all that much higher specs than your 2400c, so anything I can do on my 3400c you should be able to do on a 2400c. The applications I currently have installed on my 3400c include the following:

And as of late, I've been playing around with 3D design and animation on that system. A good example of what I've produced using the software listed above would be this short video...
... and I'm sure that it is good for word processing too.
