The ICC-141 utilizes small-scale integrated circuits, and a rather unique display system that looks like a LED (Light Emitting Diode)-based segmented- style display, but actually uses small incandescent lamps to light the segments. A nice feature of the machine, since it does use incandescent lamps which do burn out, is a button to the right of the decimal point selection slide switch that, when pressed and held down, will light all of the segments on all of the displays in order to verify that all of the lamps are working. The ICC-141 is a general four-function calculator, with a single memory register that has various accumulation modes. The machine operates in fixed decimal point mode, with the decimal point location set by a slider switch that spans the length of the display. Positioning the decimal point is simply a matter of moving the slider to the desired position. This is similar to the decimal point selection method of early Sony calculators. This machine, and a two-memory register version(ICC-142), were sold in North America by Dictaphone under an OEM relationship with Sanyo. Dictaphone-marketed models of these machines had slight variations in colors used from the Sanyo calculators, but function identically, and look nealy identical. The Dictaphone-branded calculators are also wanted for the museum.
