I spent a little time playing with ocropus and then teseract, trying
pdp-11 diags back to text. I didn't have good luck. I'd be
interested if others
have a working formula.
I did have a little fun "training" tereract on the line printer font.
I think that
technique holds promise but it needed more data to do a good job (my
was too small, but did improve things a lot).
just curious if anyone else has tried training one of the ocr programs
line printer fonts.
