I learned on the vic 20 and 64 in my computer class my senior year of high school. While out with my mom christmas shopping, the k mart had a 64 in the electronics dept. my brother was with me....I decided to enter a program.....real brief....it basically cleared the screen and posted a question....it said Hi, what's your name..... when someone would put in their name and hit enter.....the would clear the screen, and say f you and the name, then lock the computer screen so you had to shut off the computer to get back to the main menu.....
