The Fisher-Price PXL-2000 was a toy camcorder on the market only in 1987. Despite it being a toy, it actually does record video and audio to an audio cassette tape. The video is very low resolution and black and white only and the audio is mono audio, stored on one channel of the stereo audio cassette.
