it seems not one OS but 2...
first we have CPM/68k with a flat filesystem and GEM on top of that then we have GEMDOS with a msdos like filesystem and also GEM on top both are reported to run on lisa.
I now have something like a boot floppy image. But tags are missing. In fact the problem is that I run command on top of atari bios and gemdos, so I have an atari like image but a lisa boot sector. I found disc geometry modifications for sony, twiggy and profile in gemdos oem sources.
I also have the os file and the bootsector. we just need some tools to assemble this... also unassembling bootsector will help (code start at 28th byte in file boot.abs).
