Spectravision was a video game maker back in the Golden Age of the Atari 2600. They were doing great selling their games mail order only, (up until the video game crash of 1983). Many of their games are rare and highly sought after today, such as Chase the Chuckwagon and Bumper Bash. A few of their titles were only available through the Columbia House music club. (Some games are labeled Spectravideo).
Spectravision also produced the only available keyboard for the Atari 2600, the Compumate.
Today SpectraVision is known as Spectra Video. They sell a wide assortment of video game gear and accessories.
