The worst things I've done with an Amiga? Here's a few in order of importance:
1. I inverted the ROM chips in a 1200.
2. I festered around inside a 1200 without an anti-static wrist band.
3. I sold my first A2000 for money while attending college. I'm sure the money wasn't wisely spent.
4. I gave Amiga Corp. 50$ for a t-shirt.
