I've uploaded a zip archive of the gerber + drill file needed for the adapter board. The cutouts in the board are smaller than the OshPark minimum limit, so you'll need to use a different service. My original prototype board was 1.3mm thick, and I had to scrape away some of the board backing so it would clip into the palm pilot. I'd recommend a 0.8mm board if possible or be prepared to cut away some of the board thickness with an Xacto blade.
