Subject: Watford 13 board

Hellooooooo

A couple of you recently helped me work out the connections for the Watford
13 board. Now that it's working fine, there is the option of adding a couple
of batteries as a battery back up, and I believe this would also enable the
RTC (or was this another extra bit). Even if the RTC isn't on it, it would
still be nice to add battery backup for the SWRAM.

The question is do you think I would benefit from using a car battery and
jump leads or should I stick to normal torch batteries and attach them
cunningly via a couple of leads. And where should I attach these leads on
the board. I know it is going to be two of those solder pads above the RAM
chips, but which solder pads is the question.
