Once you get .TAP files, here's a link to the tools you need to extract the catalog directories, as well as decode the BASIC programs on the tape.   They work fantastic:

Once you get the tape read and have a .tap image, please put it somewhere where Time Shared BASIC fans can download it and take a look at what's there.   If it's a HIBernate tape, could potentially be fired up under SimH and run just as it was the day the tape was made.

If it's a 9-Track tape, I do have ability to read them, but no 7-track capability.  I'm in Oregon.
