The things you do when the TV has driven you mad :-) After playing around with the mechanics of the concept, it should be possible since the PIC chip can deal with the extra RAM requirements, but you fall into the original keys problem again because of the [m] and [n] function keys, although if you had a few spare keys in the parts bin you could probably paint them and add lettering. I have the PC simulation running the instructions as fast as it can, so something like AMORT which may have to execute 50,000 plus instructions and can take minutes on a real calculator, is done almost instantly, although simulation slows to normal speed with functions like PAUSE and -x- etc. The emulators at teenix.org now have this "Turbo" mode as an option as well. cheers Tony |
