a great little calculator from around 1974. this model
a basic "4 banger" machine with a six digit, green vacuum fluorescent
interesting is the use of a special arrow key (this
is not a delete button) that allows display of the next six digits of the
result. the idea was to save the cost of a more expensive display but
the display uses the half-height zero which was common in early desktop
machines (eg as-8a).
for example, 123456*654321= shows 8o7798. holding the
arrow key then displays 53376.o and so the answer is really, 80779853376.
11 digits, pretty neat.
