The Burroughs C3207 is an early Sharp-manufactured four-function electronic calculator, introduced in 1969. The C3207 utilizes NEC uPDx MOS logic ICs and a 14-digit Nixie display, and has a single storage register. The C3207 control ROM is constructed from an array of diodes. Like all Burroughs calculators manufactured by Sharp, the C3207 is architecturally homogenous with Sharp Compet calculators from the same era, being the most similar to the Compet 22 and Compet 16 models.
Sharp manufactured several slight variants of the C3200, including models equipped with a VFD readout. All bear the C3200 placard on the faceplate, but the specific model is printed on a sticker on the bottom of the unit.
