MARLEY seems to have more in common with KASETA, even though they have different file endings. `AA::` and `BB::`, a large section of `- - -`... and second byte alternation are present near the start of both, as well as the large section of `1`s (assuming this is all in ASCII). Are they all the same file format?

I'm guessing they're all from a word processor at this point - Text602 is a shot in the dark from a vague link on Wikipedia - and I think the file is structured as pairs of bytes, with the first being some data, and the latter being a presentation attribute. For example, I'm guessing from LINEN that `0x06` indicates superscript.
