List of IBM PS/2 models

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.

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]
