Martin McCormick wote:
>  I even read this on a Macintosh using preview and it came out a little
better than the Linux pdf reader named pdftotext,
but it still did not give anything one could trust.

I sometimes run pdftotext from the command line to convert pdf documents to
text.
I'm not sure how you are using it, but I ran the command
   pdftotext 40044f.pdf 4044f.txt
and the resulting text file contains the same mess that you showed for the
pin diagrams.

The '-layout' option (maintain original physical layout) can help:
   pdftotext -layout 40044f.pdf 4044f.txt
produced a text file that contains this instead (best viewed in a monospace
font):

It's not ideal, but is a lot better. Can you make sense of the above?
