So, recently, I was again working on a digital breadboard project. In this case for my MECB bus based 8-bit retro platform. And, despite having used my
8-bit LED Things regularly, with various projects, for monitoring registers, inputs, and outputs, I had a sudden thought: Wouldn't it be great, if…
