Toshiba TOSBAC Computer CPU Chip (1980s)
Item #888
This gold-tone promotional tie bar from Toshiba features a pendant that contains an actual CPU chip of the type that were used in their "TOSBAC" (TOshiba Scientific and Business Automatic Computer) computers.
Numerous models of Toshiba's TOSBAC minicomputers were developed, starting with the TOSBAC-4200 transistor based computer in 1961.
The TOSBAC-1100E, introduced in 1968, was Japan's first computer to use Integrated Circuits. The IC's used were DTL (Diode Transistor Logic) technology. In the 1980's, TOSBAC computers would evolve to using multiple 32-bit Microprocessor chips to power them.
The last model of the Toshiba Tosbac mainframe computer was the Tosbac 5000 series, which was produced in the late 1990s. Specifically, the series included models like the Tosbac 5000 and the Tosbac 5000D, with production tapering off around 1999. Toshiba eventually shifted its focus away from mainframes to other types of computing solutions.
New unused item, Comes in original plastic case with foam insert.
Timeline of Toshiba TOSBAC Computers and Their Chips
- TOSBAC-1100 (Late 1960s) - No Chips Used: Early transistors and discrete components.
- TOSBAC-1100E (Late 1960s) - Chips Used: Early Integrated circuit chips, primarily using TTL (Transistor-Transistor Logic) technology.
- TOSBAC-4000 series (Early 1970s) - Chips Used: Advanced integrated circuits, including custom and standard logic chips, further improving processing capabilities.
- TOSBAC-5000 series (Late 1970s to 1990s) - Chips Used: More sophisticated ICs, including microprocessors designed for specific applications, likely moving towards more complex architectures.

Toshiba Power Electronics IEGT Transistor Chip (1999)Item #784
This promotional tie clip contains an actual Toshiba IEGT (Injection Enhanced Gate Transistor) chip embedded on it's front with the words "Toshiba Power Electronics". The IEGT transistor, developed by Toshiba's Electronics Devices Group starting in the late 1990's, is a semiconductor device used in the fast switching of circuits in high power electronics such as electric cars, air-conditioners, sub-way trains, motor drives, renewable energy sources, and computer power supplies.
