IBM PS/2
Preliminary Information
Release Year 1987
Leak Risk Medium
Batteries Yes, BR-P2 6V Lithium for RTC and CMOS
Mounting Technology Through Hole, SMD, Sockets
Capacitor Types Aluminum Electrolytic, Tantalum, Ceramic
Destructive Entry No

The IBM PS/2 Range was a mostly PC compatible line of computer by IBM after the PC,XT, & AT that uses MCA and other proprietary interfaces for standard hardware.

Known Issues

Floppy Drive Won't Work

Causes

  • Capacitors on floppy drive leak

Solutions

  • Recap floppy drive

Disassembly Notes

  • Computer is mostly toolless to work on
  • Be careful with plastic pegs that need to be lift, use a plastic fork claw tool (a trim pop tool) if they are stuck to pry it up from underneath

Original Parts
