Photographs of the front and back of Apple’s original Mac 128k. A finger is touching the power switch on the back, and a hand is inserting a floppy disk into the front. Text below reads: Insert the Macintosh System Disk into the disk drive, metal end first, label side up. Push the disk until it clicks into place. The soft hum is your Macintosh getting information from the disk. A message appears, welcoming you to Macintosh.
