Hard to do. It's an executable. It's 400 bytes larger than the other executable I have and 266 bytes larger than the "Homesoft 5200" version.
Now I noticed that Atari Protos has 3 prototypes listed. Mid level WIP, late level WIP and Final version. Of course looking at the descriptions of differences I think it is safe to say none of the three versions I have access two are even close to the first two prototypes.
