None power on, I don't have batteries to check them. Whoever stored them, them without batteries and all battery doors are present. The ti-55 shows some distortion in the back like it got hot at one time but its not melted. Battery trays look good, not corroded or damaged, except the unisonic shows some minor evidence of old corrosion as pictured.
All in good, vintage condition. Bottom 3 pictured have cases. It has a proprietary looking battery pack in it that long ago died.
