Toshiba T1100

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". 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 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, expandable to 640 kB of RAM, and two internal diskette drives.
