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

This Homeland 8011 is a basic but very stylish calculator using a green VF-Display (Vacuum Fluorescent Display) and a solid keyboard. Unfortunately it lacks the memory known from the earlier Homeland 810.

Dismantling the featured Homeland 8011 manufactured in June 1976 by Toshiba in Japan reveals with the TMS0855 single-chip calculator circuit similar to the one found in the rare TI-150. With the basic four functions, a [%] key and the sqr-function it tops the Canon Palmtronic LD-80 using the same calculator brain.

The TMS0850 is a modification of the original TMS0800 LSI MOS chip to directly interface with low-voltage VFDs up to 35 Volts. The TMS0801 found in the Canon LE-84 used additional external digit drivers for its Light Emitted Diode display.

Later Homeland calculators switched to the TMS1000 Microcomputer family, don't miss the Homeland 8105 and 8109
