Info from RADIO SHACK:
Your Model EC-100 Electronic Calculator incorporates the very latest solid-state design and engineering. The calculator circuitry is a single-chip MOS/LSI (metal-oxide-semiconductor/large-scale-integration) with the equivalent of over 6000 transistors plus other parts! The display read-outs are high-output Light Emitting Diodes (LED's). The keyboard has a unique design, providing a positive feel and button action in conjunction with protection against false input caused by "keybounce" or other error-producing conditions. Other superior features include: internal power circuit regulation permit-ting operation from 4 to 7 volts, replaceable batteries (use standard car-bon-zinc, alkaline or rechargeable Ni Cads), battery saving automatic cut-off of LED display after 15 seconds of non-use (immediately redisplayed by a touch of the "D" key), automatic full-floating decimal operation, chain operation, automatic credit balance, automatic round-off, automatic over-flow entry indication, automatic overflow result indication, automatic low battery voltage indication. The EC-100 comes completes with AC Adapter/Battery Charger - no need to spend extra money for an accessory.
