I don't have a spare keyboard, but how about I send you an entire 6300 setup for the cost of shipping? It needs a new power supply, and the battery was yanked from it (so no leaking issue there).

Keyboard, mono-monitor and system are all a bit dirty, but otherwise in pretty good condition. Just let me know.

EDIT: Arg, just realized that Trixsters post is very old. Still I am going to leave this here, anyone interested in this thing let me know.
