Toshiba introduced the first laptop computer almost 23 years ago, in 1985.

At its launch, the T1100 featured a 4.77 MHz Intel 80C88 processor, MS-DOS 2.11 operating system, one 720KB 3.5-inch floppy disk drive (the first in a mass-marketed PC) for storage, and 512 KB RAM (it is kilobytes folks, not megabytes). The system was 12.2-inches wide, 2.6-inches high and 12 inches deep with a weight of just nine pounds.

The screen was a black-and-white 9.1- by 4.7-inch LCD with a resolution of 640×200 pixels, and optional 14.4kbps modem. The unit cost more than US$4,000 in 1985 [$7,670 in 2007 dollars].
