Holy moly, I freaking remember watching Super Book! O___O Did not until I saw it mentioned here~
The anime I remember seeing at the utmost earliest was Osama Tezuka's Unico movies, which Disney aired (more than once, honestly) in the eaaarly 80's. After that, I couldn't say what I saw in what order! Everything from Battle of the Planets, Gigantor, Speed Racer, and yes, Transformers and Go Bots! to later Dominion Tank Police, Robot Carnival, Sailor Moon, and beyond~ (I think I may have covered a decade in that selection, lol! A lot of mecha going on in my memories atm~) Also, in the early to mid 80's there was a fairy tale anime series that aired. I used to watch it frequently, but I can't remember the name.
