This is one of my older calculators. It was bought in the seventies by
my father for the bargain price of $150. It's a beauty, with a nixy tube
for every digit and LED indicators for 'overflow', 'negative' and
'battery-low'. This calculator was a great help in my early school-days!
Old though it may be, this calculator has been used extensively. You can even see that on the picture of the calculator, there is quite a bit of wear near the on/off switch!
It's really amazing when you realise that the HP 65 was introduced in the same year as this model (but, admittedly at a higher price).
