Hey! Thanks for your response.
Sorry about the confusing short-handed chip names!
The "C4" Chip is a 4-bit counter I made.
The "M41" Chip is a Multiplexer that chooses from four inputs to be sent to one output.
As for sending my save, that's good to know! I'll attach the project file in this response after I give it a once-over. That way you can see how each chip was built!
