Bread Board Computer
A bread board computer build made from TTL ICs!
Project Details / Background
In an introduction to digital systems course I took at Virginia Tech during my Sophmore we built a basic 8-bit computer in Verilog.
For me, this course really bridged the gap in my understanding – helping me to understand how hardware can be abstracted into code.
After designing the 8-bit computer in Verilog I decided that I could try and implement a similar design on a breadboard. So after making some compromises and buying RAM, ALU, and EEPROM ICs, this 8-bit computer is the result.
My design was based on Ben Eater's 8-bit computer with some slight modifications to the ISA and hardware designs. Additionally, I am still working out some hardware and software bugs.
