Cyborg 009
YouTube is a useful resource for sampling old anime not readily available anywhere else. For instance, Nanto Anime (www.youtube.com/user/NantoAnime) has, at time of writing, subtitled episodes of Cyborg 009, Ribon no Kishi, Gegege no Kitaro series #1, Magical Girl Sally series #1, and Rainbow Sentai Robin. (I never heard of the last one either, but it’s like Cyborg 009 with even less sign of having employed a science adviser).
Quality is surprisingly good – full-screen 360p & full speed with an adequate connection, but each episode is split into 3 segments.
