Need info on 6300 real-time clock

[Bruce Molay]

Is someone out there familiar with the i/o addresses for
the real time clock/calendar on the 6300?  I need to know what
port(s) to read/write to get/set the year, and what format it
uses.  I have info for month, day, hour, min, sec, sec/10  ,
but do not know how to get/set the year.  Please email answers

thanks,
