Just a quick post to Confirm that these keyboards are indeed PS2 compatible and that I have mine working on my DuinoMite board right now using an old PS2 Mouse lead.
granted all the letters are wrong (not where they should be), but they are Consistantly wrong, so it`s not a Random thing.
so I`m going to guess that because these Pi boards are sold everywhere and are Linux based that there should be a keymap file somewhere, and a way to edit it.
this of course will need the work of someone brighter than me as I have never even seen linux, but I think it should be Doable
so it`s at least One more possibility for you guys to play with!
