@Dali - thank you very much! Much easier to read like that. And it’s a shame users must perform such inversion, as manuals are not provided for daylight reading and printing (NDSP is so “manly and metal tough”, outch).
@Cheems - all the pages are white. Some of them contain tables, which background could not be inverted. Those you see as black.
I don’t get it ??? Every time I download this file, no matter which of a dozen programs I use to view it, it is still white text on a black background ???
Here is another piece to the puzzle. The file apparently is sensitive to the pdf app you are using to view the file. I tried a free version of an app called Xodo. Lo and behold, the same file appears inverted!!! Viewed in my other pdf viewing apps it appears white on black.
You should be able to host it on dropbox a bit more permanently, FWIW, although I feel like Neural should probably host this themselves, as there’s been a bit of demand for it.
