I was doing some cleaning and found a copy of the original Doom. All 4 Floppy Disks are included, the instruction booklet + pages for installation, and even the "Thanks for purchasing a registered copy..." letter.
I can't seem to find any information on a value for this so I was hoping this forum might be able to help me out. It was purchased in Australia if that makes a difference.
Everything is in near perfect condition, apart from the box (not pictured) which has a couple of scratches on it.
