Craig Electronics of Compton, California was a major distributor of stereo equipment and other consumer electronics in the 1960's. Their calculators were usually US and Japanese OEM-products with the Craig stickers on it. Most recognized was the Model 4501, better known as rebadged Bowmar 901B

Craig4510_PCB.jpg (52613 Byte)This Craig 4510 is a very unusual calculator using a 20-key keyboard with two additional switches for the Konstant and Memory functions. Dismantling the calculator reveals with the TMS0132 a rare member of the TMS0100 single-chip calculator series. From a technical point of view the Craig 4510 is related to the SR-10.
