This is not strictly necessary, as - at least for the Ricoh chip in the A3000 and A4000, as those chips' Y10 registers happily continue to count up from 0xA if manually incremented past 0x9. - the Amiga ROMs and "setclock" commands seem to interpret 0xA 0x? like 200?, etc. However, - the Amiga setclock writes the modulo 10 value into the chips - the chip docs of both chips, including the Y2K information of their manufacturers, only refer to the range 0-9 - the chips increment from 9 to 0 So we better conform to this, to avoid unpleasant surprises.
