Favorite obsolete formats.....


What are your favorite of these? I’m unsure if any stations broadcast in AM stereo nowadays. 8 track, Mini-disk, Cassette, VHS, CED, Beta, DAT, Reel to Reel, Am Stereo, Laserdisc, Quadraphonic, Dolby FM. Surely many formats have been overlooked.

Elcaset.   The convenience of cassettes with the sound of reel to reel.
I couldn't afford one at the time, and now I can't think why I'd want one.
Elcaset. That one was new to me. Thank you for mentioning it via this thread. 
I live in an area where there are still some excellent broadcast quality FM stations. Listening to music on some of these stations through a quality anaolg tuner is an amazing experience.
