In the late 70s, a toku series was created based on Spider-Man...not really much to do with the comics, but it's still incredibly bizarre, corny and funny. I love it, but then again, I'm a huge Sentai/Power Rangers fan. It has the huge fighting robo and everything.
Note - it's Japanese but has English subs. If you have half an hour to spare, it's worth checking out.
This site http://tvlinks.voodeedoo.org/ has a mother load of great cartoons and TV shows with most of them containing entire seasons. Enjoy them while you can as I am sure they will soon suffer a You Tube type demise.
