About a month ago, you wrote: The only information that needs to be changed is that the sides with the braille side up are not sides 1 and 4 but rather 1 and 3. Wrong you are, sir. You may mean stereo tracks one and three, but they sure are tracks one and four according to the audio. I'm aware Those tapes clearly announce themselves as track four and track one after the conversion is done. I used the NLS numbering system here as opposed to the stereo track numbering system, which is probably what you're referring to. I did that deliberately, assuming the stereo numbering system would be confusing to people who did the conversion. But I trust by now, you've long ago written the new and improved version of my tutorial. I'm a little behind in the e-mai. Nolan, who converts tracks one and four, then turns the tape over and converts tracks 2 and 3.
