The T1100 was 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 variation of the Intel 8088), 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, 80C86 CPU, 7.16 MHz or 4.77 MHz operation, expandable to 640 kB of RAM, and two internal diskette drives.[4]
