Can you name any software program that runs under System 6 that really needs more than 8MB of RAM? System 7, yes. But System 6 is old school. You can do a lot with very little RAM. You can even run rather "modern" apps like Deneba Canvas 3.5.6 under System 6.0.8 with only 4MB of RAM. Its when you run thinks like Photoshop under System 7 or web browsers that you begin to need more than 8 or 10MB of RAM.

RAM Doubler has its place, but keep in mind that it certainly will not speed up your computer in the process.
