On my old P475, I actually ran Arkanoid 1.1 on it. Set the video to B&W, and made sure that the computer booted in 24-bit mode. Think I was running System 7.1 or maybe 7.5 or 7.5.1 on the machine. Been 11 years since I owned it.

But, yes, get a hard drive and some more RAM. They aren't *that* expensive to source, even on evilBay.
