Does anyone have a good oscilloscope?
Found an interesting hardware initialization in Model 410, FF2, and FF3. Still working out what each register is for. The function is identical in all version of firmware in which it is found. It starts by setting $f708 (believed to control power to various parts of camera) to zero. After that, it assigns values to registers $f730-$f73f, but not in that order. Finally, it sets $fa1b to zero. Registers $f730-$f73f are only used in this function although it appears in several banks. I have tried changing the values for these registers and they definitely affect the TFT display. It would be helpful if someone with a good oscilloscope could help me identify the exact function of each. (Registers $f730-$f73f are used in the Model 400 camera for the 7-segment LCD.)
