  • The Epson HX20 is considered to be one of the world's first laptop computers.

    It included a full keyboard, a four by 20-line display, storage device and rechargeable batteries with a Microsoft Basic operating system.

    The machine was used for many years in pharmacies to send orders to wholesalers and can still be found in use today.

  • IBM's first laptop computer in 1986 was also the first machine by the company to use 3.5-inch floppy discs.

    Sales of the PC Convertible were poor, as it was hampered by a hard to read and oddly shaped LCD screen, did not feature PC serial and parallel ports and was not much faster than the Portable model that it replaced.

    The £1,800 machine ran at 4.77MHz and had 256KB of memory.

  • Apple packed a lot into its first portable computer the $6,500 Macintosh Portable, launched in 1989, with a 16 MHz processor, 1MB of memory and built-in LCD screen and trackball.
