RE: Finally I got my HP-67!
Now we need some one to make a battery case, similar to the case that holds 3 AAAs, made for the classic calculators and available on TAS (Search for "Rechargeable HP Calculator Battery Classic CASE"), but instead adapts a common (i.e. cheap) lithium-ion camera battery. I chose a camera battery as these are well supported by stand alone chargers.
