As I understand it, the Kickstart ROM wasn't ready in time for the Amiga 1000's release, so you had to boot off a Kickstart disk which loaded the "permanent" resources into RAM, then swap to the Workbench disk which loaded the GUI. So although Topaz shipped with the Amiga 1000 (on floppy disk), I wasn't comfortable calling it part of the Amiga 1000 the way it was part of the Amiga 500.

That’s correct. I had a Kickstart 1.1 disk to boot from. I feel like the Kickstart on that floppy was as much a part of the A1000 as the Kickstart on the A500’s ROM was part of it. The only difference is was the media it loaded from.
