VTC P.31 – Time for a Bit of a Redesign

Welcome back to the tube computer! It’s been a hot minute since the last episode in this series. I haven’t abandoned the project, I just was increasingly unhappy with the direction it was headed in. So, I’ve spent the last few months reevaluating what I want the project to be and redesigning a healthy chunk of it. I’m finally there with a new design I’m really happy with, so let’s dive in and see what it is!
