T3100 was a portable PC manufactured by Toshiba and released in 1986. It featured a 10 MB hard drive, 8 MHz Intel 80286 CPU and a black & orange 9.6" gas-plasma display with a resolution of 640x400 pixels.
The portable had for the time a special high-resolution 640 x 400 display mode which is similar to and partially compatible with the Olivetti/AT&T 6300 graphics. There's a single proprietary expansion slot for 1200 bit/s modem, expansion chassis for 5x 8-bit ISA cards, Ethernet NIC, 2400 bit/s modem, and a 1 MB memory card (thus 3.6 MB in max total). The base model had 1MB of memory, which could be upgraded to 5MB. 
Toshiba T3100 was not a true portable, because it needed an external power source in all except the last version.
Five versions existed:
- The T3100/20 was essentially the same as the base T3100 but with a larger hard drive (20 MB instead of 10 MB).
- The T3100e had a 12 MHz 80286 CPU (switchable to 6 MHz, 1 MB RAM and a 20 MB hard drive.
- The T3100e/40 was the same as the T3100e, but with a larger 40 MB hard drive.
- The T3100SX had a 16 MHz i386SX CPU, 1 MB RAM and a 40 MB or 80 MB hard drive, a VGA 640x480x16 shade black & orange gas plasma display or black & white LC, and also included an internal rechargeable battery, for true portability.
In Japan, the Japanese version of T3100 was marketed as J-3100.

T3100, released in 1986, consisted of an 80286 CPU running at 8MHz, but could be slowed to 4.77MHz using a keyboard shortcut. It also had 640KB system memory, which could be upgraded to 2.6MB. It shipped with MS-DOS 3.2.
