What Is Personal System/2 (PS/2)?

Do you know, the PS/2 was a real pain in the butt. The PS/2 was IBM’s third generation of PCs, introduced in 1987. The PS/2 was an advanced proprietary computer architecture launched by IBM to regain control of the PC market. The PS/2 improved architecture with a 32-bit bus, a new bus architecture, and a faster processor. It meant that it could handle more tasks at once than its predecessors, which made it easier for users to multitask. It also came with improved graphics and a sound system that could support color monitors and high-quality stereo speakers. The PS/2 included a mouse, keyboard and power supply as standard equipment. IBM released three models of the PS/2: Model 30 (286), Model 60 (386) and Model 50 (486). These were followed by two models of the PS/1 in 1990: Model 1 (286) and Model 1A (386). The introduction of the PS/2 was not well received by consumers who preferred cheaper computers from other companies like Compaq, Apple and Zenith Data Systems that used non-proprietary components such as Intel’s 486 microprocessor instead of IBM’s PowerPC chipsets. The PS/2 line was a commercial failure, but many still consider it a success. Not every day do you get to say that your product failed commercially and still consider it a success. That's correct what happened with IBM's PS/2 line of personal computer systems, which were introduced in 1987 and discontinued in 1993. The PS/2s were the second generation of IBM's Personal System/2 (PS/2) line, which debuted in 1984 with the IBM PC-AT. The PS/2s had higher price tags than their predecessors and failed to gain traction in the market due to competition from Apple Macintosh computers, Commodore Amiga computers, and other alternatives. However! Many innovations derived from PS/2 architecture were successful for many years; these included the 16550 UART (Universal Asynchronous Receiver Transmitter), 1440 KB 3. 5-inch floppy disk format (which was replaced by 720 KB floppies in 1994), 72-pin SIMMs (Single Inline Memory Module), the PS/2 keyboard and mouse ports (which are still used today), and the VGA video standard
