Between 1992 and 1995, I reverse engineered Commodore 64 applications by printing their disassemblies on paper and adding handwritten comments (in German). These are the PDF scans of the 62 applications, which are 552 pages total.

Thank you for this. 🙂
Hello, some listings are not readable, I image you used just a b/w filter discarding all the pixel below a certain threshold.
You can use imagemagik for process all the scans and get much more readable results, it requires a bit of scripting and some tries. The trick is to scan at 600dpi and use a gaussian filter, tune the contrast and then use a reasonable threshold for b/w.
If you send me some unaltered scans I can help you with this task, plus I can show you how the djvu format is good at this kind of things.
Kind Regards!
wow, serious geek-porn, thanks so much. I remember doing similar analyzing on paper (a quite noisy matrix printer with tracktor-feed, way before NLQ ) using 68000 disassembly on my trusty Amiga.
Took the liberty to script-download all these pdfs at once. real name maybe next time… Great blog.
most of those of images a faded and hard to see the source code, I would appropriate it make much clearer more readable THANKS
