Hello all, I have a quick question for you. When I boot the CMM2 it always asks for the keyboard and the time / date. I have an RTC (and I did OPTION DS3231 ON and the battery is inserted) - so how do I avoid this constant asking for keyboard / time? Thank you for any suggestions! (I am running 5.07 as 6.00 does not work at all with my keyboard) Thank you! PS: I have a picomite too - but the CMM2 behaves not exactly the same, hence the questions Edited 2025-06-21 18:40 by Gadgetguy |

Yeah, I wish there was an option to bypass the time/date input altogether. Means that no-keyboard embedded system would be dependent on a healthy battery. |

This is normal? So why is there a battery powered clock if one needs to enter the time and date every time? |

It is not normal. Your RTC is kaput, or battery is flat, or in upside down. Note the batteries in the original CMM2 had an appallingly short life span. I don't know if that is still the case. Best wishes, Tom MMBasic for Linux, Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

Having re-read your initial post I think I know what is happening. Are you using the default onboard RTC or have you installed the optional high resolution DS3231 module ? If as I suspect it is the former then try OPTION DS3231 OFF. Best wishes, Tom Edited 2025-06-21 21:17 by thwill MMBasic for Linux, Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |
