Applied Engineering, headquartered in Carrollton, Texas, was the leading third-party hardware vendor for the Apple II from 1979 until March 25, 1994.
In its day, Applied Engineering built a solid reputation among Apple II owners for their innovation, excellent build quality, and generous warranty support. They were quick to fill gaps in the market for Apple II add-on boards and expansion options, often developing products for the Apple II line that neither Apple Computer nor other third-party vendors offered.
In 1990, Applied Engineering began to market products for the Macintosh and Commodore Amiga. Because of stiff competition in already active markets and their late entries, Applied Engineering could not duplicate the success it had experienced with the Apple II, eventually going out of business.
