I've been building a Toaster computer recently. I have a VT4000, Flyer, AD516 for sound...I'm just still not sure what the rest of this equipment floating around is for

I think a short one-line description of what each portion of Amiga video production equipment is would be AWESOME, if someone were inclined to do it

For example....still not sure what exactly genlocking and syncs and things like that are for.
