From the project
A Versitile 6502 Based Microcomputer
The Versatile Micro Computer (VMC for short) is a 6502 platform designed to be Powerful, expandable, and versatile
The VMC was designed as a project to express everything I have leared in electrical engineering, and as a way to learn more concepts in electrical engineering, computer engineering and computer science
- Hardware: KiCad files for the Hardware side of the VMC - Reference: Reference documents - Software: all sorts of programs - Tools: Tools for testing

Micro: common questions
How big is the Micro PCB?
The Micro measures 200 × 150 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Micro?
175 components, from 83 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Micro design files?
From the jurendono/VMC repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Micro design in my own project?
The repository has no license, so all rights stay with jurendono. Use it as a reference, and ask the author before reusing the design.
