I have come across these in the past but never bothered to analyize them, You could may be use a scope and see if you can detect a pattern, paper tapes are written in ASCII or EIA format, I imagine these are the same as they have to be ones & Zeros I assume, and are probabally asyncronous serial.
But the big problem is if you do identify the pattern, how to transcribe off the tape to digital storage media.
