Michael Holley, left, and Allen Baum listen to Wozniak reminisce about the early days of the club. Baum helped create the Apple I and introduced Wozniak to the club. On the table is an Altair computer that was programmed to play the song "Daisy," repeating a demonstration in the earliest days of the Homebrew Computer Club. In the late 1950s, "Daisy" was the first song played by a computer, a feat some consider the beginning of computer music. Also, in the movie "2001," as the computer HAL is being gradually shut down, it begins to sing "Daisy."

John Draper, also known as Cap'n Crunch, was on hand at the anniversary party. In the 1970s, Draper was convicted of wire fraud for using a "blue box" and a toy Cap'n Crunch whistle from a cereal box to tap into the national telephone network. He also developed the first word processor for the Apple II.

Sellam Ismail, founder of the Vintage Computer Festival, talks about his own collection of 2,000 vintage computers, housed in a warehouse in Livermore, Calif. The most he paid for a single item was $400--for a prototype Apple IIGS. His rarest machine is an Apple Lisa with the original, and buggy, dual Twiggy drives.
