I came across this Mycenaen word when Iwas trapped in a Wikipaedia chain:

the verbal augment is almost entirely absent from Mycenaean Greek with only one known exception, 𐀀𐀟𐀈𐀐, a-pe-do-ke (PY Fr 1184), but even that appears elsewhere without the augment, as 𐀀𐀢𐀈𐀐, a-pu-do-ke (KN Od 681). — https://en.wikipedia.org/wiki/Mycenaean_Greek

I presume this is the third person singular aorist from ἀποδίδωμι, "he gave". Perhaps ἀπο and Latin a(b(s)) in aufero etc. are related. Is there any conexion at all between the Mycenaean u and the Latin u here? My guess would be coincidence, and a(b(s)) and ἀπο might not be related at all (I believe ὐπό is related, at least), but who knows?

P.S. I see Linear B in Firefox, although I now see that they won't show up in Chrome. Do you have a Linear B font installed? You could get the Aegean fonts here: http://users.teilar.gr/~g1951d
