Usagi Electric | Vacuum Tube Computer P.16 – Building a Full Adder for the ALU @UsagiElectric | Uploaded August 2021 | Updated October 2024, 3 hours ago.
In this episode we continue work on our ALU, this time adding in the “Arithmetic” part! We explore what a Half and Full Adder is, then we go ahead and build up the Full Adder that will be used in the machine. And then I go on a complete tangent talking about output displays, hexadecimal, 7-segment VFDs and so on. This one’s kind of all over the place, but it sure was a fun one to make, haha.
