Second it did not have VGA graphics it had MCGA (Multicolour Graphics Array). IBM still was the market leader, but it didn't like the fact that Compaq and others were taking so much business.
The line launched in April 1987 with a high-powered ad campaign featuring the former cast of the hit 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.
The company promised a new graphical OS (which I'll talk about later) that would compete with the Macintosh in windowing functionality.Even today, many new PCs ship with "PS/2 connectors" for mice and keyboards, although they have been steadily falling out of fashion in favor of USB ports.Every model in the PS/2 line contained a 3.5-inch microfloppy drive, a Sony-developed technology that, until then, had been featured most prominently in Apple Macintosh computers.The low-end PS/2 Model 30 shipped with a drive that could read and write 720KB double-density disks.
At the same time, Compaq and others began innovating ahead of IBM, such as shipping computers based on the new 32-bit Intel 80386 CPU.IBM decided that something needed to be done with these upstarts.
The ISA bus was 8- and 16-bit standard for expansion cards for a system. Starter Disk v1.0 (03-28-90, 1.44MB) Advanced Diagnostics v1.0 (03-28-90, 1.44MB) Model 25 SX. The USB port has mostly bypassed this standard, but you can still find it on some machines.The only major thing introduced in the PS/2 that you don't see today is the MicroChannel bus. Beyond that, these machines were limited to a 720Kb low-density floppy drive where other models had a 1.44 Mb high-density drive. MicroChannel's solution was to use a configuration disk. ---------------------------------------------------------------------------------------------------When IBM decided to enter the "microcomputer" market in 1981, it did so as sort of a skunk-works project.
Naturally, some of them, such as VGA, advanced over time to the standards that we have today, but they all got their start with the PS/2.The Mac introduced the 3.5" drive, but the PS/2 made it a standard.
The low-end PS/2 Model 30 shipped with a drive that could read and write 720KB double-density disks. If IBM couldn't make money off of the systems itself, it could at least have the license fees.To this end in 1987, IBM introduced the PS/2 line. Part of the problem was the relative high cost of the PS/2 over clone makers, but a lot of the problem came from the lack of adoption of the MicroChannel bus.Like Ford, which stuck by the Edsel for a few years, IBM continued to market and upgrade the PS/2 line for several years. This meant that a 1981 PC, which shipped with five slots, left little room for expansion when it already contained a graphics card, a disk controller, a serial card, and a printer card--a common configuration at the time.With the PS/2, IBM chose to integrate many of those commonly used I/O boards into the motherboard itself.
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 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.IBM announced four PS/2 models during its April 1987 launch: the Model 30, 50, 60, and 80. PS/2s running Intel's … Neither configuration included an OS--you had to buy PC-DOS 3.3 for an extra $120 ($242 today).The following chart from IBM offers a more detailed view of the systems available during the 1987 launch, and illustrates just how complex the variety could be.Every unit in the line included at least one feature new to IBM's PC offerings--and the market in general. Of the major computer makers of the time, only As noted in the link, a 23-year old Michael Dell announced a pair of MicroChannel Dell PCs, but I couldn't find any reference to Dell actually Rather than pay tribute to IBM, the very OEMs that IBM tried to fleece with the MicroChannel bus turned against it and created their own standard called EISA. Up to that point, IBM itself had favored traditional 5.25-inch disk drives.
It was only in the past two years that 1.44Mb floppy drives didn't come as standard equipment on PCs.Likewise, it was only recently that the PS/2 mouse and keyboard port fell off the radar as standard equipment. Power-on the system (8525).
IBM PS/2 Model 25/30 Printer 3.0 - 1. They ranged dramatically in power and price; on the low end, the Model 30 (roughly equivalent to a PC XT) contained an 8MHz 8086 CPU, 640KB of RAM, and a 20MB hard drive, and retailed for $2295 (about $4642 in 2012 dollars when adjusted for inflation).The most powerful configuration of the Model 80 came equipped with a 20MHz 386 CPU, 2MB of RAM, and a 115MB hard drive for a total cost of $10,995 (about $22,243 today). 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.
