About this Artwork This artwork is based on a micro-image of one of the very first computer chips. The actual chip is in the lower left corner of the artwork, and it's over fifty years old. This was a chip that could store a single bit of information. The picture below shows an x-ray view of the chip. The "chip" that you see is actually the package for the true chip. The silicon computer chip is attached to a Header and covered by the Can, so you can't see it. It is protected in the package and is connected to the outside world with Interconnect Wires that attach the chip's pads to the Leads (the tops of three of the leads are visible at the left side of the image) that allow the package to be plugged into a circuit board.
