Congratulations!
Guess what, I've just brought home A3000, too

Got it from the place where it shared the room with three cats and a dog for two or three years. You may imagine what it was like inside.
It also had a leaked NiCd battery, I've cut that away immediately. Also has an odd memory expansion module, like a small PCB with two 30-pin SIMMs plugged into main board where ZIP memory should be.
This is the first Amiga with scandoubler I now own, man its VGA output is awesome!
