    The ENIAC was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania and began construction in 1943 and was not completed until 1946. It occupied about 1,800 square feet and used about 18,000 vacuum tubes, weighing almost 50 tons.

    The first Computer Evolution
    The first personal computers, introduced in 1975, came as kits: The MITS Altair 8800, followed by the IMSAI 8080, an Altair clone. (Yes, cloning has been around that long!) Both used the Intel 8080 CPU. That was also the year Zilog created the Z-80 processor and MOS Technology produced the 6502.

    The First Laptop
    The laptop was invented by Adam Osborne in 1981. It was called 'Osborne 1' and cost $1,795. It came bundled with $1,500 worth of programmes. It had a tiny computer screen built into it.
  • The Second Laptop: The Bondwell 2

    Although it wasn't released until 1985, well after the decline of CP/M as a major operating system, the Bondwell 2 is one of only a handful of CP/M laptops. It used a Z-80 CPU running at 4 MHz, had 64 K RAM and, unusual for a CP/M machine, a 3.5" floppy disk drive built in. It had an 80×25 character-based LCD mounted on a hinge similar to modern laptops, one of the first computers to use this form factor.
  • The Best Laptop

    The one of the best laptops from apple was introduced in 2006 and this was a whole new category.
