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

This Homeland 8009 is almost identical with the 8109 model, but traded the 4-key memory for the Pi function.

Dismantling the featured Homeland 8009 reveals a clean design centered around a NEC uPD1801C single-chip calculator circuit.
