Given a word in Attic, Doric, Koine, or pretty much any other Greek dialect, I can usually find information on it through the Perseus morphological analyzer.
However, Perseus doesn't cover Mycenaean. If I have a word written in Mycenaean, such as a-ja-me-no, is there any sort of online reference work that maps it to a meaning, a later Greek cognate, or a Proto-Indo-European root (or ideally all three)?
(I'm sorely missing the university library right now, and any online resource would be helpful, even if it's not especially up-to-date.)
