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

This Homeland 80K is a typical Japanese calculator using a green VF-Display (Vacuum Fluorescent Display) and solid keyboard in a rather small package.

Dismantling this calculator manufactured in 1976 reveals a Texas Instruments TMS0855 single-chip calculator circuit known from the Homeland 8011.
