It's not a listing--it's the actual image of the EPROM.
Since it is machine language for the 6502 and data, looking at it
in a text editor is not very enlightening, but if you want to burn
it into another EPROM, it's just what you want. ;-)
If you want to "understand" the code in the EPROM, you'll
need to disassemble it into assembly language, then pick
it apart to figure out what it's doing.
Be assured that no "official" source code for the Grappler ROM
was ever published, so anything in this vein is reverse engineering.
