To run Windows 7 well you have more ram than 98se can run with. There are articles about that issue so I'll stop here. Not only that but drivers are rare today.
What's fun to do is use it to install in Virtual Box.
The original is in another computer and I intentually sent the registration number to another person who had a need for it. I don't know if it can be installed in a WIN7 Home Premium w/o a registration number.
I had really done an good upate on it, bought another 4 GB RAM, removed the 80 GB hard drive and replaced it with a 160 GB hard Drive. It was given freely to me but the giver had a professor who needed a computer. Besides, I don't need of 2 computers. Darrell
