I cannot figure out what I need to do for my speakers?

I just bought speakers from a rummage sale. They are Toshiba ss-220, 80-s-90's. They have all three speakers are 2-4 feet tall, and I need a cord for them. How would I do that? I have computer speakers, with all the cabling. Could I use that, or would i need something else? I would like step-by-step instructions, along with a URL for backup.
