Sounds great! If you are indeed serious about trying to recreate the ancient C/A/T character set in PostScript fonts (or some other font format that can be converted into a form that can be downloaded into a genuine PostScript printer), I'll try to find some time to produce the following: 1) A set of C/A/T binary files corresponding to that CSTR #54 manual, as well as BWK's troff tutorial which usually follows right after in book compilations. This step is simply a matter of running the original troff executable (with -t option) on the original source files for these docs - but since I actually run an OS that still includes that original version of troff and you said you don't, it would probably be easier for me to produce and publish these files. 2) A converter tool from C/A/T binary codes to PostScript, using whatever fonts you give it. I'll test it initially using the set of fonts which I developed for my 4.3BSD-Quasijarus pstroff - all characters will be there, all positioning will come from original troff, but it won't look pretty because most PS native font characters don't match those of C/A/T. Then as you progress with your font drawing project, you should be able to substitute your fonts instead of mine, and see how the output improves. > Nice! The more material I have, the merrier. As for the scan that Branden > and I were referring to, I've uploaded a copy to Dropbox Using pdfimages utility with -list option, I compared the image format and resolution in various scans I described in my previous mail, plus this new one you just shared, and concluded that the best quality is contained in these two: http://bitsavers.org/pdf/att/unix/7th_Edition/UNIX_Programmers_Manual_Seventh_Edition_January_1979_Volume_2A_SRI_Reprint_June_1980.pdf http://bitsavers.org/pdf/att/unix/7th_Edition/VA-004A_UNIX_Programmers_Manual_Edition_Seven_Volume_2A_197901.pdf Here are extracted PNG images of just the relevant page from both PDFs: https://www.freecalypso.org/members/falcon/troff/cstr54-fontpage-sri.png https://www.freecalypso.org/members/falcon/troff/cstr54-fontpage-ucb.png Each PNG is a lossless extract from the corresponding PDF, made with pdfimages utility. Each image is described as being 600x600 DPI in PDF metadata, and the print is said to be in 12 point - numbers for converting from pixels to .001m units in font reconstruction... M~
