Many thanks for the quick response. Of course, you're right, the model no does begin with MZ (I read it off the surface which had worn away) - you guys really know your stuff! I have a new PC with various software included. Is it likely that I can use one of these programmes or will I need to get hold of something like audacity? Is there somewhere I can download this software or is it best to get a CD (from the linked site) to upload? Ta, lnr
