Seiko ThumBoard for Palm M500
Updated driver

Note from Marshall....
When I first got my Seiko ThumBoard, I was very disappointed, because it just wouldn't work.  My Palm M500 would go into an endless loop of trying to sync with my PC.  I discovered an up-dated driver on the Seiko website, and that fixed the problem.  Just delete your old Seiko ThumBoard driver from your Palm M500, and install this one, and you should be OK.
