The Home Micro Project

Home Micro provides a series of microcomputers that can be built by hand using electronics parts that are currently in production. Parts lists, assembly instructions, design notes, software tools, an emulator, and full source code are provided, as well as a number of sample applications.

Home Micro was inspired by late 1970s and early 1980s home computers such as the Apple II, Atari 8-bit series, Commodore 64, ZX80 and ZX Spectrum. With relatively modest hardware capabilities and cost, these computers allowed generations of enthusiasts to get into computers and software development. Home Micro enables the construction of a computer with roughly similar capabilities from parts that are currently being manufactured and sold.

Two different microcomputers are in development. The HM1000 is a basic microcomputer designed to be easy to build. It offers keyboard input and monochrome video using 17 integrated circuits. The HM2000 additionally offers color video and multi-channel audio. Although work on the project is not yet complete, the HM1000 can be built today using the provided step-by-step assembly guide.
