No.20538 Tafoid Administrator Sep 16, 2022, 22:09	Seems reasonable. It shouldn't be a default configuration in any machine that is isn't expected at its base.
No.20539 Pernod Developer Sep 17, 2022, 16:53	The RTC's are implemented on the various floppy and IDE boards. In MAME we have the RTC option in coco12.cpp but it's only used in coco_fdc.cpp. The RTC option should be completely removed and appropriate RTC implemented on each applicable board.
No.20847 tlindner Moderator Nov 20, 2022, 05:22	I have a solution to this just about ready to "Pull Request". It removes the RTC from the RS Disk Controller and and adds a Disto SC-II controller with it's own option for an RTC.
