A Yomega PowerSpin body with transaxle system and a "power converter" for top play and replaceable flash discs for visual effect. You can configure the toy as either a traditional yo-yo or as a top.

The instructions to convert the yo-yo to a "Gemini top" were as follows:

"1. Unscrew yo-yo and remove spool and string, leaving string attached to spool.
2. Screw "power converter" snugly into hole on inside surface of yo half to make a top. Choose a "flash disc", slide over power converter, and press flat against surface of top."

This model was protected under two U.S. patents:

• US patent 4895547 assigned January 23, 1990 to Leonard R. Amaral of Swansea, MA for a "Superior performance yo-yo".
• US patent 5017172 assigned May 21, 1991 to C. Vaughn Seifert of Boxboro, MA, for a "Convertible yo-yo and top".

The Gemini Gyro debuted in 1989 in box-shaped packaging made out of soft plastic. The second version from 1991 was released in oversized clam shell packaging and came with additional flash discs. The Gemini Gyro seen in this exhibit was the third version. It was also the last release of the toy that could be used as a yo-yo or a top. Yomega's next release of the "Gemini Gyro" was a dedicated gyroscope.

Original retail price: $10 US.
