Lyrical Toy Box and extras

Lyrical Toy Box is like a prelude of what wee now know and love as Mahou Shoujo Lirical Nanoha. It featured Nanoha, Lindy (as a tinny fairy), Chrono (as the main antagonist) and several other characters from Triangle Heart (yes, no Fate I'm afraid). I'm currently trying to find it somewhere, but the only thing I found whas this intro: http://www.youtube.com/watch?v=G_RBghAfiW8

Also, in addition tho the original anime, there are 3 sound stages that (supposely) happen in betwen the chapters of the actual anime. Does someone know anything more about this?

EDIT: Some translations of the Sound Stages at: http://forums.animesuki.com/showthread.php?t=37267
Most of them containing some Nanoha x Fate yuri.
Also checked some of the Strikers Sound Stage 4 (called episode 27) and I feel glad that the anime hasn't continued. I don't know if Nanoha could survive another season if she uses the Blaster Sistem again.
