Adler 121PD Desktop Printing Calculator

This is a vintage Adler 121PD electronic desktop printing calculator, likely dating from the mid-to-late 1970s. The unit features a cream-colored plastic housing that shows significant yellowing associated with age and exposure. It is equipped with a built-in paper roll printer at the top and a standard numerical keypad below. The interface includes color-coded keys: a large teal '+' bar, a red '-' bar, an orange 'C/CA' key, and black secondary function keys. The number keys are light yellow with black numerals. A prominent 'ADLER 121PD' branding plate is visible on the upper right of the control panel. Condition-wise, the item shows heavy signs of use and age, including surface grime, dirt accumulation between keys, and black ink or scuff marks on several numeric keys (notably the 6, 9, and 1 keys). The teal plus bar shows significant surface wear and staining. The paper roll currently loaded is partially used and slightly yellowed. The unit retains its original thick black power cord, which appears intact. A 'Savers' thrift store price sticker of $6.99 is adhered to the top casing. Measuring approximately 10-12 inches in length, this machine is a classic example of 20th-century office technology, showcasing the transition from mechanical to electronic accounting tools.
