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. 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.
TDK SA 90s and if i wanted to splurge a Chromium Cassette tape.  $6 bucks a pop for 45 minutes of music each side.  I swear some of my greatest listening experiences were with those cassette tapes.
