Spotted over at HackerNews is a link to a detailed description of the build steps for a homebrew 8 bit (6502 based) home computer.

The pages, by Dirk Grappendorf, cover stage by stage descriptions of the implementation, including the hardware schematics, assembler listings and a prototype built up on breadboard.

This is a description of my attempt to build a simple microcomputer system with an 8-bit MOS 6502 CPU that was used in many popular home computers of the 1970s and 1980s like the Commodore 64 or the Apple II. This project was started in September 2014 and finished in January 2015. Above you can see an image of the final product. This is no in-depth tutorial on how to build a 6502 based computer system. It is more like a developer diary, which describes the evolution of the system design over time from the first simple support circuits to the complete product.

Original hackernews discussion thread.

    Don't be afraid to try SMD, I had somewhat of an apprehension. Within a day or two, I managed to do lead-free soldering of 0402 sized components by hand pretty decently. I am doing another project now, I will be using solder paste for that one, a first for me, it should be much easier than hand soldering.
