Shibaura Electric Co., Ltd., better known as Toshiba - the official name since
1978 - introduced early in their history the Homeland brand.
This Homeland 810 is a typical Japanese calculator using a green VF-Display (Vacuum Fluorescent Display), a solid keyboard and a somewhat boring styling. It could be compared with e.g. the Toshiba BC-8111 in functionality and size.
Dismantling the Homeland 810 reveals a Hitachi HD36260 single-chip calculator circuit, a chip found quite often in Japanese calculators of 1975. Nevertheless gained Texas Instruments in 1976 a lot off success with the famous TMS1000 Microcomputer family. Even Homeland calculators used them (or its predecessors):
| Model | Introduction | Calculator chip |
| Homeland 80K | 1976 | TMS0855 |
| Homeland 8011 | 1976 | TMS0855 |
| Homeland 8105 | 1976 | TMS1071 |
| Homeland 8109 | 1977 | TMS1045 |
The Homeland 810 calculator was manufactured by Systek in Japan with two different printed circuit boards (PCBs), one labeled Systek 81H sports an Hitachi HD36260 chip, a second one labeled Systek 81N utilizes a NEC µPD276 chip.
Some Homeland products were sold as OEM products to MBO, don't miss the Conti 10 and Conti 20.
