​Toshiba TOSBAC Computer CPU Chip (1980s)

Toshiba TOSBAC computer IC chip
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.

​New unused item, Comes in original plastic case with foam insert.
