Heres a construction article from Herb:

This is the approach I would use, based on my skill set. I have mad s/w

Would it not be simpler to make an optical reader
to handle this job?
You need a light source and the correct number of opto
transistors to read
the light from each hole. There is an index built into the tape so that is
easy to set.
Something like this:

Of course my assumption above is based on tape that is still complete. If
it has holes or can't be pulled then, yes, photographing and visually
reading the dot patterns may be necessary, but that sounds rather
impractical if there are more than a couple of tapes to transcribe.
