Welcome to a Laptop Ac Adapter specialist of the Dell Ac Adapter
Twenty-five years ago, IBM announced the Personal System/2 (PS/2), a new line of IBM PC-compatible machines that capped an era of profound influence on the personal computer market.
By the time of the PS/2's launch in 1987, IBM PC clones--unauthorized work-alike machines that could utilize IBM PC hardware and software--had eaten away a sizable portion of IBM's own PC platform. Compare the numbers: In 1983, IBM controlled roughly 76 percent of the PC-compatible market, but in 1986 its share slipped to 26 percent.
IBM devised a plan to regain control of the PC-compatible market by introducing a new series of machines--the PS/2 line--with a proprietary expansion bus, operating system, and BIOS that would require clone makers to pay a hefty license if they wanted to play IBM's with battery like Dell 02H098 Ac Adapter , Dell 2H098 Ac Adapter , Dell Inspiron 1000 Ac Adapter , Dell Inspiron 1100 Ac Adapter , Dell Inspiron 5100 Ac Adapter , Dell Precision M50 Ac Adapter , Dell Latitude D800 Ac Adapter , Dell Inspiron 6400 Ac Adapter , Dell Latitude D620 Ac Adapter , Dell Precision M60 Ac Adapter , Dell Inspiron 6000 Ac Adapter , Dell Latitude X300 Ac Adapter game. Unfortunately for IBM, PC clone manufacturers had already been playing their own game.
In the end, IBM failed to reclaim a market that was quickly slipping out of its grasp. But the PS/2 series left a lasting impression of technical influence on the PC industry that continues to this day.
When IBM created the PC in 1981, it used a large number of easily obtainable, off-the-shelf components to construct the machine. Just about any company could have put them together into a computer system, but IBM added a couple of features that would give the machine a flavor unique to IBM. The first was its BIOS, the basic underlying code that governed use of the machine. The second was its disk operating system, which had been supplied by Microsoft.
When Microsoft signed the deal to supply PC-DOS to IBM, it included a clause that allowed Microsoft to sell that same OS to other computer vendors--which Microsoft did (labeling it "MS-DOS") almost as soon as the PC launched.
That wasn't a serious problem at first, because those non-IBM machines, although they ran MS-DOS, could not legally utilize the full suite of available IBM PC software and hardware add-ons.
As the IBM PC grew in sales and influence, other computer manufacturers started to look into making PC-compatible machines. Before doing so, they had to reverse-engineer IBM's proprietary BIOS code using a clean-room technique to spare themselves from infringing upon IBM's copyright and trademarks.
In June 1982, Columbia Data Products did just that, and it introduced the first PC clone, the MPC 1600. Dynalogic and Compaq followed with PC work-alikes of their own in 1983, and soon, companies such as Phoenix Technologies developed IBM PC-compatible BIOS products that they freely licensed to any company that came calling. The floodgates had opened, and the PC-compatible market was no longer IBM's to own.
At least in the early years, that market did not exist without IBM's influence. IBM's PC XT (1983) and PC AT (1984) both brought with them considerable innovations in PC design that cloners quickly copied.
But that lead would not last forever. A profound shift in market leadership occurred when Compaq released its DeskPro 386, a powerful 1986 PC compatible that beat IBM to market in using Intel's 80386 CPU. It was an embarrassing blow to IBM, and Big Blue knew that it had to do something drastic to solidify its power.
That something was the PS/2. The line launched in April 1987 with a high-powered ad campaign featuring the former cast of the hit MASH TV show, and a new slogan: "PS/2 It!"
Critics, who had seen more-powerful computers at lower prices, weren't particularly impressed, and everyone immediately knew that IBM planned to use the PS/2 to pull the rug out from beneath the PC-compatible industry. But the new PS/2 did have some tricks up its sleeve that would keep cloners busy for another couple of years in an attempt to catch up.
