Thanks to all.

I tried a soft reset very early on in the process. In fact, I've tried
it several times

While looking around Paul's site (thanks for all the info you
provide), I saw that the cradle I have will also work with the 3700
series ipaq. I have one of those lying about unused. That should allow
me to confirm or eliminate the PDA.

Sounds like a project for the next unflyable day.
