PB 86 R, PB 486T, and Force 486/25 CPU Upgrade Information

Warning Only authorized service personnel should upgrade the system. Anyone who wants to upgrade the system herself/himself should know about the dangers of ESD (Electro-Static Discharge) and the necessary precautions. Unknowingly zapping the components of the computer will void the warranty.

The CPU may be replaced with the Intel Overdrive Processor. The Overdrive chip must be removed and the original CPU installed before any onsite service. Due to the dangers of ESD, either process must be done by an authorized service center technician for systems still under warranty. Intel has tested the Overdrive Processor in the FORCE 486/25.

Note
The 486T motherboard uses 238 pin type 2 socket.
 

Upgrade CPU type
DX2ODPR50
 

Math Co-Processor
This system does not have an Upgrade Socket, but the CPU socket has an extra pin hole to accommodate the overdrive processors. The socket is a zero insertion force (zif) socket with a lever arm to pop out the CPU or put it back in. The appropriate overdrive processor to use in this system is the ODPR486SX-25.
 
The Weitek WTL4167 co-processor can be installed at location U52.
