Building a 4bit / 8bit computer in CPLD

8_Bit_Computer_by_Ben_AndersonSomething we’ve been working towards is building a homebrew CPU from scratch in CPLD. If you’ve seen any of our “Getting Started with CPLDs” guide, you might have noticed that we’re working towards completing the ALU before we can start adding proper CPU features to it. This article is less about the CPLD side of things (we’ll continue with the guides) and more about the rest of what we’ve been doing.

Building things on breadboards is fine but I often find that I either need to pinch something from the design, I knock wires out of place or there’s some other reason that it gets destroyed. In order to get round this, I’ve started building a modular control panel for my ongoing project. I’ve named it…. The Carlputer… ahem.
