What kind of AC adapter does the 200LX use?
CAUTION: It’s different from the 95LX! The 200LX uses 12VDC, negative tip, up to 750mA, approx 5.5mm OD barrel-type connector. Plugging in an adapter with a positive tip, or one that puts out AC instead of DC, will kill your palmtop’s adapter jack and you’ll be left to battery power alone. This is fixable, but not cheaply.
