Intel 80486 overdrive
Overdrive/upgrade processors for 80486 systems could be used to easily upgrade
single or double clocked 80486 processors with double or triple clocked 80486 CPUs.
Two different types of 80486 overdrive processors were offered:
- Processors with "ODP" in their part number could only be used in special overdrive sockets. When inserted into the overdrive socket they would disable the original processor.
- Processors with "ODPR" in their part number replaced the original processor.
Almost all overdrive processors were sold with integrated heatsink.
