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 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.{{cite web|title=Toshiba's flyer for the T1100|url=http://minuszerodegrees.net/manuals/Toshiba/Other/Toshiba%20T1100%20-%20Flyer.pdf|accessdate=18 December 2016}} Its original price was {{USD|1899|1985|round=-1}}.
