Olympia CD200

Display is 10 digits, amber discharge tubes.

4 function.

Main integrated circuits - Solitron (?) SD9018, SD9019, SD9020A, SD9021, SD9022, all date coded to mid-1971.

375 x 149 x 80 mm (14.75" x 5.9" x 3.2").

Made in Japan, for Olympia Werke AG., Wilhelmshaven, Western Germany.
The circuit boards are marked with the logo of Matsushita, the parent company of Panasonic.

Probably one of the ugliest calculators ever made - it is basically a matt black slab.
Also the display is level with the front of the keyboard which makes it awkward for viewing while entering numbers.
At this time the integrated circuits were expensive and so are mounted in sockets for easy replacement should a fault occur.
