Usagi Electric | Vacuum Tube Computer P.23 – Electrostatic, Rotating Drum and Core Memory @UsagiElectric | Uploaded February 2022 | Updated October 2024, 10 hours ago.
We’re back baby! It’s time to get right into building the tube computer again! Although, before we start building anything, we’re going to take a quick little aside and have a closer look at some different types of memory that were used on vacuum tube computers back in the day and look at why they weren’t necessarily going to be the best option for us. So, come join us as we try to figure out just how exactly all the weird memories used to work!
