I have the actual mechanics of it working, but try as I might, it is just too complicated trying to sort out the various functions and math behind them. It is way more than just a printing version of the HP-80. I don't think I could ever guarantee a proper outcome.

Not criticizing, but curious: what is the problem? If you can emulate the hardware and you have a ROM image, doesn't the math take care of itself?
