That brings me back. I found a unloved computer at school which I got to keep after graduation, since it was going to be tossed away anyway. Already obsolete at the time since several years. Pentium 166Mhz stock, and a whopping 128MiB of RAM. Pretty unimpressive, but after some searching online I found that you could flash the BIOS to a beta version and change the multipier jumpers, and then get access to an incredible 400Mhz AMD K6-2, if installed in the CPU socket.

I believe you can both guess what I did next with that information. :D
