I’m very sorry to hear about your grandmother as well. Both of mine are long since gone but I always smile when I think about them looking down on me and not having a clue about anything I’m doing but being proud of it anyway.
As for your hint book request I submit this:
A reader and contributor to SierraVault bent over backward and sent me a CD full of carefully scanned Hint Books (almost the full collection). About half of these are the ‘hidden red text’ variety and the other half are the later straight print versions. On the red text books the contributor, Vasyl, spent a significant amount of time tweaking the settings on his scanner so that a scan could be made that would ‘see through’ the red ink. In recalling what he wrote to be about the process he indicated he had somehow altered the settings on his scanner so that it was scanning with a different wavelength of light. It isn’t often you can knock an electrical engineer on his butt but this guy shocked and impressed me. The scans of those books include a scan of the page in it’s original format followed up with the altered scan of the same page so you can read the questions and answers.
Rather than duplicate work I encourage you to pull these PDFs down from SierraVault and use them here in whatever way you want. If you do so, would you please be sure to credit Vasyl with the work?
Good luck with the site. I’m looking forward to seeing what you pull together.
