This MBO ALPHA 902 is obviously a rebadged Toshiba SLC-8410, we know with the ALPHA 502 already a sibling of the SLC-8261.

MBO International Electronic GmbH, Jena was founded 1973 and started with the MBO Junior the production of the first portable calculator in Germany. Later MBO placed their name stickers on Far-East OEM products.

Dismantling this MBO ALPHA 902 scientific calculators doesn't reveal any surprises, it is 100% identical with the Toshiba design and sports even the prominent SANSYU logo.
