===== History and Trivia =====

Following the success of the ColecoVision, Bit Corporation produced a clone system featuring a second cartridge slot which made the system compatible with Sega SG-1000 carts, the Chuang Zao Zhe 50.

Later, Telegames imported the system in the USA selling it as the Personal Arcade system (actually, until 1988 units had the name Dina 2-in-1 on the system, which probably was simply a Bit Corporation redesign of the original Chuang Zao Zhe 50).

While the compatibility with both ColecoVision and SG-1000 cartridge was for sure appealing, the system design had some flaw: while two controllers were available, only one set of numeric key was present (on the console itself), making some Coleco 2-players game impossible to be used.

Also, the compatibility with SG-1000 was not advertised at all by Telegames, which only sold the system as a Coleco compatible machine. Of course, the presence of a Pause button which was not working with Coleco games and of a second cart slot might have puzzled many of the owner.
