The 6502 is an 8-bit microprocessor introduced in 1975 for $25. At the time, the 6502’s competition, the Intel 8080 and the Motorola 6800 were each selling for $179. The processor was an immediate success. It found its way into many iconic consumer electronics, such as the Apple I, Apple II, Atari 2600, Commodore 64, and a version of the chip is the brains in the original Nintendo Entertainment System (NES).
Thankfully, the 6502 is still being produced today, and there is a large group of home computer makers who are ready to share their knowledge with you. Over at 6502.org, user Garth Wilson put together a primer for making your own 6502 computer. Garth will walk you through sourcing components, construction, programing, and debugging your own 6502 computer.
Garth’s goal with this primer is to “give a good grasp of computer design basics, so that with good construction, you can make a computer that works on first try, with no hardware troubleshooting.”
