Pacific Gas and Electric Logo

Pacific Gas and Electric Logo

The complex circuitry of a Motorola 68HC05PG microcontroller contains a small logo containing lightning bolts and a small silicon building that probably represents the Pacific Gas and Electric company. The chip housing the logo is known as a cuda integrated circuit, and was recovered from an Apple motherboard and uncapped by Antoine Bercovici in Paris. Cudas are microcontrollers that serve as the managing circuitry for the Apple Desktop Bus and the computer real-time clock. The chip supervises system power and maintains the parameter random access memory (also referred to as the PRAM), as well as managing and maintaining information regarding all system resets from various commands (for example, keyboard restart, loss of power, and software restart). Also Nested within the circuitry is a silicon stork carrying a new baby.
