There is a way to delete the chips you already made but editing them would be painful because you have to work with text files and not an actual editor, anyways
- Close the game
- Go to %userprofile%\AppData\LocalLow\Sebastian Lague\
- Open the folder with the game's name
- Go to SaveData
- Open the folder with your project's name
- If you created that chip it should exist as a text file :
Example : ALU.txt
- You can open that and look but if you want to delete just delete that text file and open your save again
