Borrowed a scanner and digitized the 1976 Gottlieb Royal Flush manual + schematics. The schematics I had to piece together from about 11 separate scans, but it came out OK. I haven't cleaned any of this up, so you will view it warts and all.
I figure even if people don't have this game, they might be interested in checking them out.
Manual is individual JPEGs in a ZIP file.
The schematics JPEG is 5 MB in size.
The schematics PDF is 150 MB in size. If I eventually clean it up, it will get a lot smaller, but I don't have the time, currently.
