Tokyo
Shibaura Electric Co., Ltd., better known as Toshiba - the official name since
1978 - introduced early in their history the Homeland brand.
This Homeland 8105 is a typical Japanese calculator using a
green VF-Display (Vacuum Fluorescent Display), a solid keyboard and a somewhat boring
styling.
Dismantling
the Homeland 8105 reveals with the TMS1071 the first LSI MOS
chip of the TMS1000
family using integrated display drivers. We know it already from the TI-2550 II
introduced in 1975. The TMS1071 was soon replaced with the TMS1045 and Homeland
introduced the model 8109.
