I booted your disk image on my Amiga 1000 tonight. It somewhat worked (although interestingly I could only type once I removed an external real-time clock that normally piggybacks on my keyboard line, and I encountered a lot of disk errors that would go away with a few retries), but the screen scrolled right off the bottom of my monitor. Since I'm using RGB mode on a stock Amiga 1080 monitor, I presume the issue is that the system is using extra scanlines that are only appropriate for European Amigas. You may want to add support for setting a different screen mode.
