Probably will be of help. This one was easy, comparatively. I've got yet another "mystery tape", but it has standard labels and appears to be raw data for some program (said program, of course, having disappeared). The question I don't ask myself is "exactly what will anyone do with this stuff?". Card images are mostly numeric data, arranged in fields, but no information of what the fields are, for example.
