The Jornada-Palmtop battery isn´t available anymore
(unlike the other Jornada batteries
).
The best way is to buy a cheap defective Jornada
(680/720
) and to refurbish the battery. That way I ended with two very well usable Jornadas and a spare battery
Perhaps you get a docking station, too, but most important is the serial cable which is really rare.
Don´t expect much from the HPs original manual. It says: "Put it in the dock, charge the battery, switch it on, calibrate the monitor and have fun with the online help"
