You made a great find with your A2000!
I'm curious what you want to do with it. I usually mentally categorize other Amigans into several camps (emulators, gamers, collectors, those enamored with the OS/HW, and, hardcore folks who will NOT use any other platform even for modern tasks, etc). This will have some bearing on how you continue. Example: a gamer may feel retargetable graphics (RTG) is a waste when coupled to an 030. People in the other categories might feel RTG is essential.
