The same holds for HPs firmware for the same chip (10bii+, 12C+, 15C LE, 20b/30b). This saves a lot of energy but it looses the 4KB RAM between keystrokes. Your GC would be quite busy if you were doing it in a similar way. Running the GC would probably cost more then turning the chip off could save. Are you planning an emulator so that more people will try the user interface? Marcus von Cube Wehrheim, Germany http://www.mvcsys.de http://wp34s.sf.net http://mvcsys.de/doc/basic-compare.html |
