Computer software:Coleco Adam High Speed Digital Data Pack Cassette

Released in 1983, the Coleco Adam is a home computer system manufactured by Coleco. The company hoped to follow in the success of its video game console, the ColecoVision, but due to production problems and hardware difficulties, it sold less than 100,000 units overall. The Adam's greatest asset was its large software library, which was compatible with the ColecoVision. Unlike its competitors such as the Commodore 64, the Adam sold as a complete system with computer, tape drive, printer, and pre-packaged video game, making it an attractive option for consumers. However, hardware issues such as energy surges during startup, defective tape drives, and unreliable data pack drives drove sales downward. Coleco also made decision to use the printer to spply power to the entire computer, meaning that if the printer failed, so did the rest of the hardware. Coleco attempted to boost sales by re-issuing a new manual and lowering the price, but this proved unhelpful, and the company discontinued the Adam less than two years after its release.
