This ancient and present retro few places you can see!
Compaq Computer Corporation was founded in February 1982 by former employees of Texas Instruments - Rod Canyon, Jim Harris and Bill Murtaugh. Finding investments were successful, and already in the first year the company began to grow rapidly and to unfold.
The first product was announced in 1982. It was a portable IBM PC compatible personal computer Compaq Portable, it can be called an ancestor of laptops, to which we are accustomed today. The computer was based on the Intel 8088 microprocessor and was a commercial success, partly because of lower prices than those of competitors.
In the following years the company has started the production of desktop computers, and even later servers. As you know, the price war is one of the most efficient on the market, so trying to maintain prices, Compaq became the first manufacturer of computers using processors from AMD and Cyrix.
Once the territory of the US market was not enough, Compaq entered the European market, and in 1989 the corporation has become the second European supplier of office PCs, ahead of Apple and Olivetti.
The history of the company can talk long and interesting, but it ends in 2001, merging with another powerful computer manufacturers Hewlett-Packard.

Fast forward to 1993! year and see what the company produced.
