I'm a geek at heart. Being a Mac user, there isn't much demand for knowing the ins and outs of hardware and the OS, but sometimes it's indispensable.

Online Tech Journal (MOTJ) is the place to go for information about serial port throughput, a comparison of the various Macintosh CPUs, and other interesting tidbits hard to find on the web.

Articles are listed by category. Several of these resources are on other sites.
