Anyone know any sites to watch old anime?

I've been wanting to watch some old animes from the 70s or 80s but I don't know what site to find them on i really wanna check out macross:do you remember love?

The only Old Anime I have on my Plex is Ronin Warriors. But this is a torrent site you can get it on. https://nyaa.si/?f=2&c=1_0&q=macross
