The Personal System/2 or PS/2 was a line of personal computers developed by International Business Machines Corporation (IBM). Released in 1987, the PS/2 represented IBM's second generation of personal computer following the original IBM PC series, which was retired following IBM's announcement of the PS/2 in April 1987. Most PS/2s featured the Micro Channel architecture bus—a closed standard which was IBM's attempt at recapturing control of the PC market. However some PS/2 models at the low end featured ISA buses, which IBM included with their earlier PCs and which were widely cloned due to being a mostly-open standard. Many models of PS/2 were made, which came in the form of desktops, towers, all-in-ones, portables, laptops and notebooks.
Notes

- Explanatory notes
- Built-in or optional monitors are CRTs unless mentioned otherwise.
- The Space Saving Keyboard is a 87-key numpad-less version of the Model M.[1]
- The 25 Collegiate, intended for college students, had two 720 KB floppy drives, maxed out the RAM to 640 KB, and came packaged with the official PS/2 Mouse, Windows 2.0, and four blank floppy disks.[1][2]
- Financial workstations came packaged with a 50-key function keypad and were intended for use in banks.[1][3]
- LS models are "LAN Stations": essentially the same as their non-LS counterparts but without floppy drives or hard drives and that connect to networks using Ethernet or Token Ring adapters (in essence, diskless workstations).[4]
- Ultimedia models shipped with a microphone and included SCSI CD-ROMs, M-Audio sound adapter cards and volume controls and headphone and microphone jacks at the front of the case.[5]
- Array models are PS/2 Servers with support for RAID.[6]

On Tuesday, IBM released the first product developed by [Jose] Garcia's team: the Model 25 SX. The new model uses the same Intel 386SX microprocessor ... to run the graphics-rich software popular with teachers. It will be able to display up to 256 different colors and come standard with connections for overhead projection systems and computer networks. The new models will become available in April at $1,249 to $1,899, IBM said.

IBM doesn't advertise the PS/2 as a factory-floor machine, yet the PS/2's backplane bus structure, Micro Channel, appeared in a factory-floor computer before the PS/2 itself came on the market. People who examined the IBM 7552 Gearbox, ostensibly a factory-hardened version of the AT, notice something odd about the unit's bus: It had more bus lines than could be accounted for by the AT bus. The extra lines turned out to be the 16-bit Micro Channel. Nobody at IBM said anything about it at the time, because PS/2 hadn't yet been introduced.
