The ColecoVision is Coleco Industries' second generation home video game console, which was released in August 1982. The ColecoVision offered near-arcade-quality graphics and gaming style along with the means to expand the system's basic hardware.

In 1986, Bit Corporation produced a ColecoVision clone called the Dina, which was sold in the United States by Telegames as the Telegames Personal Arcade. The main console unit consists of a 14×8×2 inch rectangular plastic case that houses the motherboard, with a cartridge slot on the right side and connectors for the external power supply and...
