Apple 1 Glamour Shot

Thought I would post a glamour shot of the 'ol Apple 1. On a more technical note, I was always annoyed that you couldn't clear the screen programatically. The clear-screen button has to be manually pressed. However, I noticed that the CA2 pin on the 6820 is unused and could be, with a simple mod, be made to clear the screen. Wonder why Woz didn't do this is the first place?
