The original iPhone has already turned 12 years old and still continues to surprise us. Apple spent years developing the iPhone, a device that had two code names that are known: “M68” and “Purple 2”, and now after all this time again appear more details about its creation.
The great secrecy of the project meant that some engineers were working on the iPhone’s headset without being able to see the rest of the device. Thanks to this, which was a requirement of Steve Jobs, there was no leakage of the original iPhone.
To keep the design secret, all the components of the original iPhone were tested on a motherboard that had nothing to do with the final design. This first prototype EVT (engineering validation test), internally called “M68”, has arrived at the hands of The Verge that has revealed some details.
The iPhone M68 prototype did not look like an iPhone
At first glance, this iPhone prototype does not differ much from a PC’s base square a few years ago. However, it was necessary to keep the project secret. In this prototype the engineers could test the components but without revealing more details.
In the image above you can see all the components and connections that this iPhone prototype had. It emphasizes in the left part the connector of 30 pins, in the corner of down to the left we have the buttons of volume and the camera and on the right to the right the slot for the SIM card. The screen and the start button are located on the bottom right.
Right in the center of this prototype we have the heart of the iPhone, the Apple processor created together with Samsung and called K4X1G153PC, an ARM processor at 620MHz. The history of Apple processors is also very interesting.
Best of all, this system has continued to work for years at Apple to prevent leaks. It is known of the existence of this type of plates in the development of the iPhone 4, although they were already smaller. Currently, they are no longer used.
