SHARP Pocket Computer PC-G850 The power wouldn't turn on when I pressed the ON button after inserting batteries, but it turned on when I pressed the reset button, and then the ON button worked. There are vertical lines on the LCD screen. The buttons all seem to work, but the response is a little sluggish. (I haven't tested all the button functions) I've mostly forgotten how to use it, so I've only confirmed that a simple BASIC program runs.
