A PERSONAL HOBBY COLLECTION CENTERED AROUND MY FIRST COMPUTER

 

 

 

The Dina, also known in Taiwan as the Chuang Zao Zhe 50 is a home video game console of the third generation originally manufactured by Bit Corporation, later sold in the United States by Telegames as the Telegames Personal Arcade. It is a clone of both the ColecoVision and Sega SG-1000 consoles, with one cartridge slot for each platform, and came bundled with the game Meteoric Shower, which was built into the system.
