Toshiba T1100
The Toshiba T1100 is a laptop manufactured by Toshiba in 1985, and has subsequently been described by Toshiba as "the world's first mass-market laptop computer". Its technical specifications were comparable to the original IBM PC desktop, using floppy disks (it had no hard drive), a 4.77 MHz Intel 80C88 CPU (a variation of the Intel 8088), 256 kB of conventional RAM extendable to 512 kB, and a monochrome LCD capable of displaying 80x25 text and 640x200 CGA graphics. Its original price was 1899 USD.

The T1100 PLUS is a later model of this laptop, released to the market in 1986. Some significant differences to the T1100 are, 80C86 CPU, 7.16 MHz or 4.77 MHz operation, 256 kB of conventional RAM (16-bit) extendable to 640 kB, and two internal diskette drives.

The T1100 was named an IEEE Milestone in 2009.
