Toy-clock problems

     We are newcomers to the net, so this may be old or redundant.

     Do other 750's running 4.1 lose their date after a reboot or powerdown?
Does anyone have a fix?

     I notice the 780 hardware handbook states that the LSB's of the
time-of-year clock may not be written.  Does this apply for 750's?  Does 4.1
obey this restriction?
