Overview

This blog documents my journey in constructing an 8-bit relay computer, from scratch, made from tons of solder, wires, lights, relays, sweat, tears, swearing and money.

The design of the computer is based on the one constructed by Dr. Harry Porter at Portland State University (reproduced on this blog with kind permission) but the construction method is my own and so this blog captures the thoughts, experiences and pitfalls that I encounter along the way.

For more information about the 'whys and wherefores' of building a computer of this type these posts are a good starting place:
  • It begins ... the first post
  • Why? ... musings on why I'm doing all this
  • The three Rs ... further musings on where to start the journey
An overview of the architecture used in this relay computer can be found in the following posts:
