Playing an MP3 SD card in an 8-track player

Neat little video about how old 8-track to cassette tape adapters worked. Compared to what we have today, the circuits and engineering are quite simple obviously, but at the time they were probably quite amazing feats of engineering.

Later on in the video, the video shows how an MP3/SD Card to cassette adapter works through one of these 8-track to cassette adapters. Audio quality, no doubt, suffers, but the uselessness of this experiment is why I love this channel.
