If you’ve ever thought about getting down to bare metal and building a homebrew computer from scratch [Garth Wilson] put up a great primer to the 6502 (http://wilsonminesco.com/6502primer/index.html), the same CPU found in Apple ][ computers, BBC Micros, Vic-20s, and the venerable Commodore 64 (a 6510 in the C64, but it's close enough).
In his guide to building a 6502 computer, [Garth] goes over all the basics – what you want the computer to do, how to decode addresses, and other important technical requirements for getting a homebrew project running.
If that’s not enough, [Garth] directs his readers to the fabulous 6502.org forums (http://forum.6502.org/) where just about every topic is discussed. The guys on the forum have a standardized I2C pinout (http://forum.6502.org/viewtopic.php?f=4&t=2155) for the 6502, allowing noobs to easily connect pre-designed keyboards, displays, and storage devices to their projects. There are a ton of tutorials (http://www.6502.org/tutorials/) on the 6502.org site, more than enough to get a homebrew project off the ground.
If you’d like to see what you can do with a homebrew 6502, check out the homebrew projects page (http://6502.org/homebuilt) featuring a 6502 Nixie clock (http://6502.org/homebuilt) and CLPD-based 65816 single board computer (http://www.pc65816.de/en/index.html). There’s a treasure trove of information here, just waiting to be pulled from the vine.
