I think new firmware is a good way to go. I would vote for a completely
new byte code, perhaps similar in spirit to the original, but designed
fresh from the ground up. There is no source for the current firmware,
although there is pseudocode for some of it, so rewriting the firmware from
scratch is somewhat inevitable already.
If somebody wants to propose a new byte code and machine model (preferably,
the compiler writer), I might be able to assist in the coding of new
firmware, having all the information for writing new firmware here at my
fingertips.
