It doesnt show up under My Computer as new drive in the system? Or you have a card reader..how are you going about getting it to talk to the 98 machine? Once you have that down you should just be able to copy them off...or perhaps this is the very problem?
98 is a ***** with USB if thats what your using, you will need to install the software and drivers first. then reboot and then plug in the camera. Or download the software for that type of camera.
