Forgot about my "Elcaset" deck Made by Technics in the late 70s it took a huge cassette that had three colors of quality. Blue was the lowest and all you would ever need. The unit automatically sensed the tape type. I pulled and pushed the tape which was the size of reel-to-reel tape and it ran at twice the speed of a regular cassette.
I had a guy at the stereo store going on and on about the Nakamichi Dragon how it was the best and highest quality cassette deck ever made. So I lugged this monster into his store....game over. I think retail was close to $2K back then and I got it on the base PX in the Philippines for $200. Format never caught on and eventually sold it but it was a stud!
