I've actually aligned the other tape drive pretty well with a program
I've found for the C64.
It obviously can see only the digital version of the signal, but the
alignment with one of my old tapes was successfull. It can read now
very reliably those tapes (and the ones written with my other C2N

That will allow me to save some PET programs until I find a better
