Tokyo Shibaura Electric Co., Ltd., better known as Toshiba - the official name since 1978 - introduced early in their history the Homeland brand. 

This Homeland 810 is a typical Japanese calculator using a green VF-Display (Vacuum Fluorescent Display), a solid keyboard and a somewhat boring styling. It could be compared with e.g. the Toshiba BC-8111 in functionality and size. 

Dismantling the Homeland 810 reveals a Hitachi HD36260 single-chip calculator circuit, a chip found quite often in Japanese calculators of 1975. Nevertheless gained Texas Instruments in 1976 a lot off success with the famous TMS1000 Microcomputer family. Even Homeland calculators used them (or its predecessors):

Model Introduction Calculator chip
Homeland 80K 1976 TMS0855
Homeland 8011 1976 TMS0855
Homeland 8105 1976 TMS1071
Homeland 8109 1977 TMS1045

Some Homeland products were sold as OEM products to MBO, don't miss the Conti 10 and Conti 20.
