Re: [ATM] OT: Desktop RPN calculator

There was a technique for rejuvenating the nicad batteries with a capacitor
discharge.  The theory was that this burned away micrscopic metal whiskers
inside the cells that were draining the power.    It worked several times,
and then finally you were done.   I do not know HP's business plan; maybe
that is where they got the idea they now use with their inkjet cartridges!

Ken,

The power packs were my problem. I would cut the case apart at the glue line
and put in new cells. What finally ended it's use was loosing several
segments of the LED display. I bought mine in Sept. 1970 for $212.00. Used
it up until three years ago. I sure do miss that RPN calculator.
