Right but the disassembled commentaries are not written by the people who originally wrote the code, so if that site is to be believed the 'original' comments and source are not around for things like the kernal and other Commodore-specific bits. It seems like an odd thing not to have surfaced given that by this point we have things like OG Quickdraw and Karateka code.

Edit: I missed the comment downthread that says that some of that code was released a couple of years ago.
