#DISCRETE TRANSISTOR COMPUTER FREE#
For this project you will need: 1.) A power supply 2.) Breadboards + lots of wires 3.) LED's for output 4.) Various logic IC's (discussed later) 5.) Free time 6.) A willingness to mess up and learn from mistakes 7.) A lot of patience Optional (but very useful): 1.) Oscilloscope 2.) Digital multimeter 3.) EEPROM programmer 4.) Sonic screwdriver Useful Links for a Project Like This: Digital Computer Electronics: TTL Cookbook:
I hope that you all enjoy and get something out of a build like this, I know that I sure did. If you already have a sound understanding of boolean logic and the workings of binary feel free to skip to the meat of the project. This is because there are many ways to approach this project.
This project also leaves many of the design aspects of the computer up to you and serves as a guide for building your own computer. This means that the end product of this Instructable will be a computer that you can program with a unique instruction set. Lastly we will then move onto the function of the various parts of a simple-as-possible computer (with a few modifications) as described in Malvino's text Digital Computer Electronics. After that, the fundamentals of binary and boolean logic will be described. This project will start off by describing the basics of electronics. Don't be afraid to try, you can only learn. This project is intended to help anyone interested in building their own computer and gaining the wonderful knowledge that comes along with the process. When it comes down to it, a CPU is fairly simple in operation once you learn the fundamentals behind all of its processes. Building an 8-bit TTL computer sounds like a daunting and complicated task, or at least it did to me when I started out on my journey to understand the architecture of a basic CPU.
