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 tool less 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
