I am interested in expanding my meagre collectionand have seen a HP 67 for sale with the following info :
"I FOUND THIS CALCULATOR IN A BOX FROM A HOUSE CLEARANCE. I WAS INTERESTED ENOUGH TO PURCHASE A BATTERY FROM AMERICA TO SEE IF IT STILL WORKED. WHILE WAITING FOR MY BATTERY I DID SOME RESEARCH ON THE INTERNET TO FIND THAT THESE ARE STILL VERY MUCH LOVED BY PEOPLE TODAY.
MY BATTERY ARRIVED WHICH I FITTED TO THE CALCULATOR & SWITCHED THE ON BUTTON.
(1) IT STARTED WHIRING & PUSHED OUT THE MAGNETIC CARD THAT WAS STILL INSIDE THE MACHINE.
(2) THE RED L.E.D DISPLAY (For lack of better words) WENT CRAZY!
(3) THE CARD FINISHED BEING PUSHED OUT & THE L.E.D DISPLAY SPELLED OUT THE WORD (Error)
(4) THE L.E.D THEN DISPLAYED A MINUS FOLLOWED BY MULTIPLE ZEROS (See picture)
(5) AT THIS POINT I WAS READY TO DO SUMS BUT COULD GET IT TO DO NO MORE THAN CHANGE THE ZEROS TO NINES BY PRESSING TWO BUTTONS AT ONCE (See picture)
(6) I TRIED TO REINSERT THE MAGNETIC CARD BUT THE MOTOR DID NOT RUN AGAIN.
THE BATTERY PACK HAS NOW RUN OUT OF POWER & I DO NOT HAVE A CHARGER SO BEING SOLD AS SEEN & AS DESCRIBED FOR REPAIR."
In answer to a question the seller said " Hi, This calculator is in excellent condition with no wear to the silver lining or keys & no scratches on the outer case. The battery compartment has no corrosion as when i got the calculator there was no battery pack inside. The overall condition is near mint as it has probably been in the protective soft case unused for many years. I hope this helps your decision"
My questions are (if you don't mind) :
1. What sort of money is it worth bidding for a working HP67
2. Do the error messages etc. seem to be resolveable ?
3. Do you think the card reader might work?
4. Is it easy to get batteries to use in an HP67 or alernatively a charger to power up these batteries ?
Many thanks for your help.
