Pottel, I don't do anything via a computer but I do have a system for transferring cassettes to CD. It's a little complex but I can do it - or, rather, I could do it. Unfortunately, that system is not set up in our new home and won't be for some time. However, the CD-Recorder is set up here and, following the prompt in the earlier posts, I have got my trusty TCS-350 back into action. I'll see if I can think of a quick fix, if only to produce a sample from which to judge whether it's worth getting the rest transferred.
