Just saw this on Audio Database, I don't think it's been posted before? https://audio-database.com/TechnicsPanasonic/amp/rs-g800-e.html
This is from Sharp's 1984 Catalog, these models were super-expensive! The CT-5001, which was also branded as the GE Roadshow, has a killer blue stereo mc player, I've never seen that color before.
From page 17, the Technics RS-M212 Component Deck with Microcassette deck. What a beauty! This is the 1981 JDM Tape Deck Catalog Listing, big money back then.
JVC D-M3 from 1982-1984, they even had JVC Branded Microcassettes. Unfortunately they don't have pricing listed. 1982 1983 1984
I think I have a handful of Sharp, Fisher and maybe Sanyo (Metal) but not many. I do have a lot of mono tapes, some with gold on the labels are really frustrating.
