Theorysonic Pyramid was launched on January 4, 2000, in El Kadsre with the price of $199. It has 4 player controllers, CD-ROM, DVD-ROM and a USB output for saving data, downloading content, playing multimedia and backup, while its controller has two analog sticks, a digital pad, four action buttons, two action triggers, built-in speakers and a built-in Page orientation color LCD screen. The Pyramid is the first and only game console to gain access to the web with the customized version of the Star Web browser built-in the console. The Pyramid is TS-UGOS-based and it’s fully compatible with TS-UGOS games. It has similarities to the Sega Dreamcast.
Theorysonic Pyradesk is a unproduced two-in-one TheoryDesk and Theorysonic Pyramid which Theorysonic planned to release alongside the Pyramid in January 2000 with the retail price of $650. Theorysonic cancelled the Pyradesk in November 1999, citing fears that it would become the commercial flop like the VRBuddy due to its power issues and it would dilute their marketing for TheoryDesk VM.
The sales declined following the popularity of most Portosic devices, more powerful consoles, and mobile gaming. It failed to outsell the Nintendo Gamecube, PlayStation 2, and Xbox 360. In 2006, no new Theorysonic home video game consoles released following lackluster sales, instead of focusing on work Portosic, TheoryPhone, and TheoryTablet devices and TS-UGOS computers for gaming. Over 17 million units sold worldwide during its lifespan. The console finally discontinued on April 30, 2011.
The Theorysonic Pyramid has over 400+ games.
