First generation Olympia electronic calculator. High end of the RAE 4/30 series, with three memory registers. Functionally identical to the Monroe 770, which was a cosmetically modified version of the RAE 4/30-3 (keyboard color changes, badging, power switch location, and overflow/sign indicator form) marketed in North America by Monroe.

Check out the Old Calculator Web Museum exhibit on the Monroe 770 for more information.
