I use the Accu-check pocket compass software on my PDA, I'm not 100% sure whether it will work on the Palm pilot, but if your pilot OS is Palms operating system and not windows based then it should work on it..
The Accu-Check pocket compass you can up load BGs from a lot of htere meters, via infered, it comes with a carb/bolus wizard, you can put in carbs, insulin ect..
Give there customer services a phone, and ensure that you explain you want the Pocket Compass software other wise they might do as I did and send you the compass software for a PC and not the one for the Palm... Even though I have both, they did supply it all free though.
