I remember reading the history of it, and it was a relatively small thing. The guy made a blank board and it greatly improved his touch typing skills. He got a lot of interest from his friends, so he started mass manufacturing them. I'm sure after the success of the first, he had enough money to rebranded the Chery G80-3000 for his second (das II). Then had Costar mass manufacture the third (das Ultimate). All of them came with no legends, and the third was the first time you were able to the buy the keyboard with inscriptions on the keys
