To All,

It is not necessary to use the Drivewire clock if you have a hardware clock in a 
cart on your Coco. Just use the software clock in NitrOS-9 and my swread programs.

Refer to the SmartWatch (r) drivers.

The cart containing the DS1216 can be in any MPI slot. I have mine in an RS-232 
pack replacing the original ROM.
In Basic, SWREAD.BAS reads the clock and creates a new string DATE$. When you 
PRINT DATE$ you get something like TUE NOV 29,2016 04:37:11 PM. SWSET permits 
turning the SmartWatch off to save battery life, using it as an elapse timer, or 
as a clock. You can select 24 or 12 hour usage.
SWREAD behaves differently under NitrOS-9. You put a softclock in OS9Boot with 
swread engaged in the startup file. Swread has the option of reading at selected 
intervals to prevent wasted overhead constantly reading the hardware clock. So
swread 10 <>>>/2&
will read the hardware clock every ten minutes.
