Peter wrote in about his experience with the Digi-Comp II:

I just wanted you and the entire Evil Mad Scientist team to know that the Digi-Comp II was a big success.  I used it to explain digital computers to a group of second graders and fifth graders. In an age of iPads and smartphones, it’s surprisingly hard to demonstrate the beauty and magic of digital computer.  The Digi-Comp II was perfect, looked great, and worked flawlessly. Thanks!
