Hi,
Another alternative.... if you have access to a different Amiga and can locate a Kickstart 1.3 ROM image (e.g. from an A500), you could use "writekick" to write out a fresh Kickstart disk...
Have a look

P.S. Was going to dig my A1000 out and experiment, but it's buried under an ancient Macintosh (oh, the treachery!) and I'm too lazy to untangle the mess of cables around it! :-)
