I am loath to updating because I really do not feel the need to.
So far, I have 3rd party apps that I built (with some necessary mods)
on f20. I do not wish to go through all the rigmarole again on f22 or
the impending f23.

No, it is not digitized yet.

I have a good (I will not say high) sony tape player with
stereo audio out (1/4 inch stereo port).
My laptop is the Dell E6510 with Intel i5 2.67GHz quad,
and 8GB ram and oodles of swap (embarrassingly 32GB :)  )
On the laptop, I have the stereo audio in and audio out.
I also have the necessary cable.
