Appendix A—Pentium OverDrive
Processor Data Sheet
The Pentium OverDrive processor is a single chip upgrade for any 5
Volt Intel486 processor system with a Pentium OverDrive processor
socket.
The Pentium OverDrive processor employs a high speed 3.3 Volt
Pentium processor core and integral fan/heatsink cooling.
This list describes the features of the Pentium OverDrive processor:

Processor
Floating Point Unit
Bus/Core Speed
Internal Cache
Cooling Unit
Voltage Regulation
**Support of the internal write back data cache is system-dependent.
If the system does not support a write back interal cache, the cache
operates in a write-through manner, similar to a standard Intel486
processor.
