Seems reasonable. It shouldn't be a default configuration in any machine that is isn't expected at its base.

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.

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.
