The Olivetti Logos 9 calculator was released in 1980. It featured a built-in printer, and was the world's smallest printing calculator at the time. It was the first Olivetti calculator to feature an LCD screen.
The calculator features the basic four functions, as well as calculating averages, totals, percentages, and the time. It had a 12-digit display with add mode and full-floating or fixed position decimal. The built-in thermal printer used paper cartridges that had space for 1300 entries. The calculator was powered by rechargeable batteries or power supply.
The Logos 9 calculator was designed by Mario Bellini, a renowned Italian designer and architect, and is an example of his minimalist designs. Bellini became a consultant for Olivetti in 1963 and continued to work with the company into the 1980s, designing many of the company's iconic products.
This example in our collection is complete with manual, power supply case, and spare paper refills.
