first consumer product, this electronic hand-held calculator made everyday math quick and
easy. The TI-2500 performed four arithmetic functions (addition, subtraction,
multiplication and division) and had a red, eight-digit light-emitting diode (LED)
display; it used an adapter to recharge the batteries. Announced in April 1972 with a
suggested retail price (SRP) of $149.95, the price was reduced to $119.95 when the product
was formally introduced on September 21, 1972.
