I am having a little trouble with my Rug Warrior board, and
I was wondering if anybody can suggest avenues to
explore in troubleshooting it.

I can download a program just fine into the board, and at 
first it executes it without any trouble.  But after a
few minutes it begins to get flaky, and before long it
stops running altogether and goes comatose.  Sometimes
it trashes the pcode interpreter as well.

I have looked at all my solder joints and they seem to
be OK, and as I said, I can download the pcode interpreter
and run IC programs OK -- for a little while, anyway.

I do not have the LCD hooked up to the board as yet, but
I do use the piezo speaker a great deal with my test 
programs.  Can the piezo buzzer flake out the board?
I will try to run a test program which does not use the
buzzer, and see how long it can go before it flakes out.

Patrick
