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".[1] 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 lower-power 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.[2] Its original price was $1899 USD.
The T1100 PLUS is a later model of this laptop, released to the market in 1986.[3] Some significant differences to the T1100 are: 16-bit data bus 80C86 CPU, 7.16 MHz or 4.77 MHz operation, 256 KB of conventional RAM (16-bit) extendable to 640 KB, and two internal 720 KB 3.5" diskette drives.[4]
The T1100 was named an IEEE Milestone in 2009.
