History of Laptop Computers

History of Laptop Computers






Modern Laptop
It is a little hard to determine what was the first portable or laptop computer, the first portable computers did not look like the book-sized and folding laptops that we are familiar with today, however, they were both portable and lapable, and lead to the development of notebook style laptops. I have outlined several potential firsts below and how each qualifies, many of the off-site links provide good photos of the computers that will let you see the progression in design.

The First Laptop? Maybe


The Grid Compass

Designed in 1979 by a Briton, William Moggridge, for Grid Systems Corporation, the Grid Compass was one fifth the weight of any model equivalent in performance and was used by NASA on the space shuttle program in the early 1980’s. A 340K byte bubble memory lap-top computer with die-cast magnesium case and folding electroluminescent graphics display screen.

Gavilan Computer As The First Laptop?


Gavilan Computer

Manny Fernandez had the idea for a well-designed laptop for executives who were starting to use computer. Fernandez, who started Gavilan Computer, promoted his machines as the first “laptop” computers in May 1983. Many historians consider the Gavilan as the first fully functional laptop computer.
The First Laptop Computer – Osborne 1

Osborne 1
The computer considered by most historians to be the first true portable computer was the Osborne 1. Adam Osborne, an ex-book publisher founded Osborne Computer and produced the Osborne 1 in 1981, a portable computer that weighed 24 pounds and cost $1795. The Osborne 1 came with a five-inch screen, modem port, two 5 1/4 floppy drives, a large collection of bundled software programs, and a battery pack. The short-lived computer company was never successful. (second photo)
