Info: This calculator is identical to the TI-1250 sold under different names from the Western Auto company. The most common names are "Electronic Wizard" or "M4987", but later also obtained the confusing "Citation" plate. The only difference from the TI-1250 is the wooden template and the missing TI logo.
