Hi, i just recently got and old Mac, Power Macintosh 5500, and i was wondering if its possible to install an old version of Unix on it, i want to learn Unix im already using the Terminal on my Macbook but i wanted to use the 5500 for something. If its not possible what's the oldest version of Mac the 5500 supports? I hope some can help me, i don't want to waste the 5500 :/
