1.1 Raspberry Pi

A Raspberry Pi computer is recommended to program the various ICs that require programming, such as the computer's ROM. The Raspberry Pi's GPIO pins give it the flexibility to implement all the necessary protocols, and at $35, even the top of the line model is quite affordable and may in fact be cheaper than buying dedicated programmers for the ICs that go into the Home Micro.

A number of different models of Raspberry Pi are available. The tools and circuits in the Home Micro repository require a Pi with the 40-pin GPIO header (which excludes some early models). The following models have been tested and are known to work:

  • Raspberry Pi 3 Model B.
  • Raspberry Pi 2 Model B.

More information about the Raspberry Pi, as well as ways to buy a Raspberry Pi, can be found at

Use of the Raspbian operating system on the Raspberry Pi is recommended.

1.2 Oscilloscope

An oscilloscope is not technically required to build the Home Micro computers. It can be an invaluable tool in visualizing what goes on in a circuit and to find and fix problems, but good oscilloscopes can also be quite pricey. It may be worth the investment if you plan to do electronics projects regularly. The signals in the Home Micro get up to 14.31818MHz, so to be most useful, an oscilloscope would have to work up to frequencies higher than that.

2 Software

To build the source code in the repository, you will need the following software:

to use the Makefiles
C compiler
for the tools and the emulator
to build the AVR code
to assemble the 6502 code
to build the emulator

On Raspbian, you can install these by running:

aptitude install binutils-avr gcc make xa65 libxcb1-dev
