Hi all, Per requests, and to satisfy my own curiosity, I've posted PDF files of the RT-11 system reference manual alongside the tiff images. These contain the images with the text underneath (i.e. you actually view scans of the original manual but it's fully searchable). A little bigger than the straigt tiff images, but it's nice to be able to execute a find... I tried to do an OCR only version of it, which *looked* very nice. The problem was that processing an old manual, on yellowing paper, well, it wasn't too accurate when dealing with punctuation. Which kind of blew any chance of a hands-free OCR, since it was turning colons into t's and so on. After a few hours of hand-correcting through chapter 3, I gave up. Any other suggestions are welcome, thanks to all the good feedback so far... Cheers, Aaron Oh yeah, it's available at www.retrobytes.org
