I've done that a while ago, but always forgot to share it:
a fully commended TOS BIOS/XBIOS listing for TOS 2.06, TOS 3.06 and ST-Book! The 3 switches allow to see the differences between all these TOS versions.

Here the (trivial) assembly code for the 2nd part of an Atari ST-Book ROM containing a ROM disk:
https://gist.github.com/sarnau/6a4f1bde ... omdisk-asm
And the disassembly for the POWER.PRG in an Atari ST-Book:
https://gist.github.com/sarnau/c2766522 ... okpowerprg
And the registers in an Atari ST-Book based on the sparse documentation, my disassembly (see above) and looking at the schematics of the board:

Hope you like it.

Nice work. Myself disassembled TOS 1.04 BIOS/XBIOS/GEMDOS/BLITTER part - so all except AES and Desktop. Not much comments there, but it works reassembled.
Only one complain - title is a bit misleading - someone may think full ROM listing

Famous Schrodinger's cat hypothetical experiment says that cat is dead or alive until we open box and see condition of poor animal, which deserved better logic. Cat is always in some certain state - regardless from is observer able or not to see what the state is.
