There are many ways to flay this hog, this is more of a thought experiment than a recipe for a TI-CH337. The ultimate hack would be to use a more modern version (with "high-res" screen) and replace/amend the guts with something which emulates the calculator - wabbitemu seems to work just fine [1] - but can also function in other ways. Add some key combination to switch functions and you have a mean lean cheatin' machine. [1] http://wabbitemu.org/ http://wabbitemu.org/
