The President models were related to the Sporting Life SETTLER, a calculator designed specifically for betting shops.

[1][2] The silver paint used was of poor quality and was notorious for wearing off.

[1][3] Both models were the same size, and intended for desktop use, being slightly too large to be readily portable at 160 by 94 by 28 millimetres (6.3 in × 3.7 in × 1.1 in).

[1][3] The President Scientific added logarithmic and trigonometric functions[3] and was powered by a General Instrument CF-599.

[5] The Settler had National Semiconductor DS8881N and MM5799NBX/N chips, and was slightly larger than the President, at 163 by 93 by 29 millimetres (6.4 in × 3.7 in × 1.1 in).
