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 leaking
Solutions
- Recap floppy drive
Disassembly Notes
- Computer is mostly toolless to work on
- Be careful with plastic pegs that need to be lifted, use a plastic fork claw tool (a trim pop tool) if they are stuck, to pry it up from underneath
