[Coco] Drivewire client for OS9/68K

[Sean]

Shelf life is 10 years.  (for the CR2032 - standard in BIOSes and lots
of other stuff.)

I have a Radio Shack calculator that still works after 7 years, but I
know a Sega Saturn's battery to hold high scores only lasts about 2
with no power connected the whole time.  Both using the CR2032
batteries.
