Help1942,
Some of us still use the older Macs and have plenty of spare parts and accessories. The key is finding a Mac User Group by googling your geographic area to find one of us. We happen to be in Washington State and could help you in a heartbeat.
When someone says that their computer died, the first question to ask is if the hard drive died or a power supply. If the hard drive died without a backup, you have an expensive data recovery process to explore. If the computer died because of some other cause, the hard drive can still be put into an external drive and data copied over to another drive.
Your first task is to find someone who has all the tools. What you are asking is a very simple matter for someone with plenty of older computers on hand. Please give more information about what the computer is doing. Does it still make noise when you turn it on? Does it chime? Does the hard drive click? Is it just the monitor that does not come on? Do you see a flashing ? when you turn on the computer. Every noise means something different.
