This is where a Mac User Group can help. The computer has educational value only. I can name a recycler in Seattle, WA who can help with the parts and pieces you need. We are in Spokane, WA and offer hands on help to youth groups. Otherwise, you are going to have to pay someone for the tools. Another option is to take the hard drive out and put it into an external case and plug that external drive into another computer.
The bottom line is that you need to start up the computer from a CD or system floppy. If you do not have that, you need to find it. If you find it on ebay, you have to decide how much money you want to spend on your education or hobby.
Post back with the name of a large city near you. That will help identify possible user groups.
