The Power Macintosh G3 AIO was the most powerful and practical beige all-in-one Mac ever made. Its design language was cluttered, confused and tooth-like… a rare example of function over form. It was sold exclusively to the education market, so they are getting harder to find.

I came across this Molar from a long-closed school. It has been scraped around a moldy garage for many years, so hopefully we can save it!

Once we get it restored, I have a few modifications that I would love to try out too.
