HP-29C now has dots across the display...

Thanks all.

AFAIK, the low power display is a single blinking decimal point, where it should be. In the 45 years I've owned this baby, I'd never seen this behaviour for low battery power.

Yes, brand spanking new Duracell double A batteries. Tested. I'd cleaned the contacts with the pink eraser when I'd changed the batteries to be sure.

Puzzling, but it appears to be fine for now.

Thanks!
