At some point the simplest answer is to type it all in again.  I've been doing work on old software using old listings.  Some are nice and clean and OCR just fine.  Some are so muddy that they are hard to read for humans, and utterly hopeless for OCR.  It's no fun to type in 300 pages of assembly code, but sometimes that's the only way.
