While researching on Astro Boy I found out that via the MangaEntertainment Channel at youtube you can actually watch the Robotech Episodes Online.

Even before Robotech came out I was already a fan of Macross. So I got surprised when somebody told me that the US version was different from the original series. And that the entire Robotech Franchise was just 3 Japanese cartoon series that had no relation to one another and was joined to create it.
