December 25, 1977: Steve Wozniak spends the holidays building a prototype of the Disk II, the Apple II’s revolutionary floppy disk drive.
“I worked all day, all night, through Christmas and New Year’s trying to get it done,” Wozniak recalls in his autobiography, iWoz. “[Early Apple employee] Randy Wiggington, who was actually attending Homestead High, the school Steve and I had graduated from, helped me a lot on that project.”
Wiggington takes December 25 off. Woz does not.
