Are you sure there is no BDM connector somewhere (or 10 "unused"

It depends. Ir may be possible, or may be not (some may be hidden
under the CPU, and there is no way to contact themin such a case).
And it depends on how much effort you put into this - and if the box
is worth such an effort.

Without a detailed hardware documentation (read: schematics) and/or
sources for the existing software it will be definitely non-trivial
to get anything else running on such a board.
