No need to shout...

Well, isn't the NVRAM just a clock + battery + RAM on a chip?  At least, in my
4/60 it is.  Anyway, if my memory serves me right (I do have a Sun 4/110 at
home, but didn't open in for ages) the 2816 and the clock are fed by a 3V
battery, so the complete set is (at least from a users point of view)
compatible with an NVRAM.  Therefore, you can edit it with the 'q' command
in the monitor.
