Overclocking my Power Macintosh 8500

Many years ago, probably around 2002-2003, I had the opportunity to raid a local computer store’s e-waste pile where people would drop off unwanted computer items behind their store. I found a lot of neat things there but one particular item was the Newer Technology PowerClip 604, which allows you to overclock the PowerPC 604 processors found in certain models of Power Macintosh 8500 and 9500. I couldn’t even use this as I didn’t own a compatible machine, but I figured it would someday become rare enough that I might be thankful I kept it. I ended up forgetting about it and it sat in my storage until the other day when I realized I now owned a compatible system; a Power Macintosh 8500/120 which I had just recently picked up. This video is my experiment with overclocking the 120MHz CPU module up to 150MHz.
