Vacuum Tube Computer P.25 – New VFDs for the Processor

On every big project, there's a point where you have to redo some work previously done, and that’s exactly what we’re doing in this episode. The IV-15 VFDs I used as indicators for the Processor just aren’t working right, so let’s take a look at what I did wrong, how we’re going to fix it, and then get to work cutting new boards and soldering them up!
