Before we build the 8-bit registers for our computer, let's design and build a 1-bit register. The 8-bit registers we'll actually use in our 8-bit computer will be simplified. We're going to take a big shortcut—using the 74LS173—described at the end of this video. But before we get to that, this video shows how we could build a 1-bit register using more basic components.

See https://eater.net/bbcpu8-registers for more. Complete parts list (everything in this video): - Clock circuit from https://youtu.be/SmQ5K7UQPMM - 1x 74LS04 (Hex inverter) - 1x 74LS08 (Quad AND gate) - 1x 74LS32 (Quad OR gate) - 1x 74LS74 (Dual D flip-flop) - 1x LED - 22 gauge wire - 5 volt power source (e.g., a USB phone charger)
