The Toshiba T1000 was a laptop computer manufactured by the Toshiba Corporation in 1987. It had a similar specification to the IBM PC Convertible, with an 4.77 MHz 8OC88 processor, 512 KB of RAM, and a monochrome CGA-compatible LCD. Unlike the Convertible, it includes a standard serial port and parallel port, connectors for an external monitor, and a real-time clock.
Unusually for an IBM compatible PC, the T1000 contained a 256 KB ROM with a copy of MS-DOS 2.11. This acted as a small, read-only hard drive. Alternative operating systems could still be loaded from the floppy drive, or (if present) the ramdisk.
Along with the earlier T1100 and T1200 systems, the Toshiba T1000 was one of the early computers to feature a "laptop" form factor and battery-powered operation.
