In 1982, Tajima introduced the world's first electronic chenille embroidery machine, called the TMCE Series Multi-head Electronic Chenille Embroidery Machine. In the same year, they developed the automatic frame changer, a dedicated apparatus for rolled textile embroidery. Also in 1982, Pulse Microsystems introduced Stitchworks, the first PC based embroidery software, and the first software based on outlines rather than stitches. This was monumental to decorators, in that it allowed them to scale and change the properties and parts of their designs easily, on the computer. Designs were output to paper tape, which was read by the embroidery machine. Stitchworks was sold worldwide by Macpherson.
