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.
