The Toshiba T100 was a modular transportable computer built around the Z80A. Its main unit combined keyboard, processor and disk storage, while users could connect a colour monitor or a compact optional LCD.

The T100 illustrates Toshiba’s experiments with portable professional computing before the IBM-compatible T-series laptops that later made the company famous.
