Brand: Toshiba

The Toshiba SR-230 is an electronic calculator released by Toshiba in 1974. It was a highly innovative and popular calculator of its time, featuring a compact design, LCD display, and memory function. The SR-230 used four AA alkaline batteries to power its circuits and could perform basic arithmetic operations such as addition, subtraction, multiplication, and division. Its successor, the Toshiba SR-310, introduced functions like square root and percent calculation. The SR-230 was one of the earliest handheld calculators to have a LCD display, which became a standard feature in subsequent calculator models. It is now a collectible item among tech enthusiasts and vintage computer collectors.
