Default Re: Roberts R600 - Very High Current Draw!

I've repaired a number of 1980's/1990s Hewlett-Packard calculators where the capacitor across the battery (here used to power the memory device to preserve its contents when you change the batteries) had gone very leaky and would flatten the batteries in an hour or so.
