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. The base model had 640KB memory. 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 2 MB memory card (thus 2.6 MB in max total). T3100e 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:
BYTE in 1989 listed the T3100/20 as among the "Distinction" winners of the BYTE Awards, citing its "amazingly clear" display and hard drive.
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.
