/* Bugs */ No, Different sources use different modes. Some use binary, others use BCD. It's left to the program to decide.
* Register 32h can be only '''either''' bcd '''or''' binary (not both)
* Register 32h documentation does not specify whether it shall be BCD or Binary
* Register 32h source code supports only two centuries (19 and 20) this is probably due to misunderstanding the RTC chip datasheet (which sorts of suggests the 8bit RAM location can contain only two different values, which is total nonsense)
* Whether other RAM locations are reserved for whatever purpose (like info about connected 40/80 track drives) is unknown
