While the Apple II was already established as a successful business-ready platform because of Visicalc, Apple was not content. The Apple III (Apple 3) was designed to take on the business environment. It was released on May 19, 1980.
The Apple III was a relatively conservative design for computers of the era. However, Steve Jobs did not want the computer to have a fan; rather, he wanted the heat generated by the electronics to be dissipated through the chassis of the machine, forgoing the cooling fan.
Unfortunately, the physical design of the case was not sufficient to cool the components inside it. By removing the fan from the design, the Apple III was prone to overheating. This caused the integrated circuit chips to disconnect from the motherboard. Customers who contacted Apple customer service were told to “raise the computers six inches in the air, and then let go”, which would cause the ICs to fall back into place.
Thousands of Apple III computers were recalled and, although a new model was introduced in 1983 to rectify the problems, the damage was already done.
