Shipping was 50£ but I don't regret it.
Ohh Man that's a pain. Bad luck. That damage looks pretty comprehensive…
Understand the urge to resurrect it. A500+ is a rare beastie. It's possible some of the tracks and components are in the same state as the Gary socket. But I hope not/
Hate to see such Amiga enthusiasm hit a wall.
Tell you what, if can’t get it working as a consolation I can send you a working Plain A500 with v5 Motherboard, For Free, postage only.
Don't give up on it.
