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.
