Here you will find an archive of the tons of reference papers and documentation presented to the arcade community that was originally hosted on Bob Robert's website. As it appears that he is no longer providing his services to the community, I wanted to be able to preserve his vital contributions and vast knowledge for all current and future arcade enthusiasts.
Below are a list of all files that comprised of Bob Roberts Bulletin Board. Files can be accessed via my Google Drive at:
