The history of computer: Some of the earlier mechanical counting machines lacked the technology to make the design work. For instance, some had parts made of wood prior to metal manipulation and manufacturing. Imagine the wear on wooden gears. This history of computers site includes the names of early pioneers of math and computing and links to related sites about the History of Computers, for further study. This site would be a good Web adjunct to accompany any book on the History of Computers or Introduction to Computers.

Who invented the computer?” is not a question with a simple answer. The real answer is that many inventors contributed to the history of computers and that a computer is a complex piece of machinery made up of many parts, each of which can be considered a separate invention.

The history of computer:

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.

Finally in 1986 a true laptop was created by IBM called the IBM PC Convertible. I say true because unlike a few of the others, this laptop didn’t have to be setup everywhere. And unlike the others it featured two modern 3.5 inch floppy drives, and space for an internal modem! Also found on the Convertible was an LCD screen and basic applications the user could use to create word documents, and schedule appointments.

Maybe most interesting was that the IBM PC Convertible sold for $3500! Of course you would be hard pressed to find that price tag on any laptop these days(They have gone way down).

Since the late 80s many manufacturers have come forward to produce new machines that are even faster and more powerful than their previous counterparts. These days the buyer has a lot of choice, and laptops are faster than ever.
