NRZI is not self clocking if you co

Fortunately, they mention that the tapes they worked with were in good

Neat.
The software mentioned in the article sounds very interesting. It talks about
starting with digital data streams from the 9 hea
Spinning at 50ips probably helped instead of the default 20
I would have digitized the tach signal too, but luckily it wasn't needed
Sad neither you or I are mentioned in the credits
I'm going to try it as well, since I have all the hw to try it out.
