7400 competition entry: Drum machine

Christopher created a Drum Machine for the Open 7400 Logic Competition. He also documented it in a video below.

The idea for building a drum machine came from a discussion I had with my roommates in which we were talking about the popularity of drum machines as simple web applications. I decided to try to implement one, but using 7400 Logic Chips. The design was rather simple and is based mostly around utilizing sequential logic devices in order to count, step through and play different tones.
