STM Electronics Corp. (Menlo Park, Calif.)

The Pied Piper I was sold as a lightweight portable computer, but it’s not a true portable without its own video display. A two-line LCD was available as an option.

The portable and desktop versions of the STM Personal Computer used similar enclosures. On the portable, the detachable keyboard attached to the case upside-down covering the LCD. A cover replaces the area where the LCD and keyboard attach on the desktop case.
