VTC P.35 – Building the Output Register

Our DIY vacuum tube computer is making excellent progress. In this episode, we need to get the output register built, but it is subtly different to the scratch register, which is going to take a little bit of a change in the PCB design to knock out. So, let’s take a look at how the scratch register was built and then how we have to change that to make the output register work like we need it to!
