Ben Eater | Testing our computer's registers - 8-bit register - Part 5 @BenEater | Uploaded 8 years ago | Updated 2 days ago
In this video, we test the register we built in the last video (youtu.be/CiMaWbz_6E8) and connect it to two more registers like it.

After this video, we'll have three registers built and tested:
- A register
- B register
- Instruction register
