Do you think forcing a [CLX] key or clearing some register values (of the 16 status registers) will do? Open to suggestions. The HP-41 wakes up by executing location 0000. The carry flag status says whether it was on or off (coming from light or deep sleep). Whether the calculator is on or off is decided by the LCD being on or off. The 10 minute auto-off or stay-on logic (non-programmable "ON" instruction) is determined by whether the LCD is enabled or disabled when the HP-41 is in light sleep (LCD is on in light sleep). If you emulate the above, the HP-41 mainframe (firmware) will take care of the rest. HÃ¥kan |
