The Digital Micromirror Device (DMD) was recognized as an ASME Mechanical Engineering Historic Landmark in 2008. Its development began in 1977 with the forming of a small team at Texas Instruments headed by noted physicist Larry Hornbeck. Texas Instruments was given a project from the Department of Defense to create a device that could modulate light.

The ABACUS II, designed and built by Texas Instruments, was the first practical automated production machine for the assembly of integrated circuits. Using heat and pressure, it bonded fine gold wire to microscopic contacts on the silicon chip and pin connections on the package.

The ABACUS II could maintain a positioning accuracy of ± 0.00025 inch while bonding up to 375 devices an hour. Following the success of this prototype, almost 1,000 ABACUS II wire bonders were built, making the economical mass production of integrated circuits a reality.
