Palm Pilot 5000 Personal Digital Assistant (1996-1997)

Palm Pilot 5000

The Pilot 5000 was one of the first two PDAs released as the First-Generation Palm devices on March 10, 1996. The device was released alongside the Palm Pilot 1000. Both these devices were very similar to the second-generation Palm devices (the Pilot Personal and Professional), but lacked the backlight feature the later models possessed. In 1997, Palm was sued by Pilot Pen, and was forced to remove the "Pilot" from their product names.
