Hmmm, I did not know that DAK was still in business.
There are some programs which allow you to record from the sound card. You can also get a MP3 recorder/player (which is what I have) and can use to record the tape and then transfer it to the computer. The nice thing about this method is that some mp3 recorders have the ability to make multiple files based on the lack of sound, which worked really nice in transfering the tapes since I did not have to watch it all the time.
One thing that I found that the default recorder on Windoze was limited in time, so it would not record for long enough. There are some free programs, but I forgot the name since I did not need them.
