OVERDRIVE
Story
​
The Overdrive was an Intel invention to transform your old 486 into a superior model, without the need for large investments.
This allowed, for example, to upgrade your 486 DX-33 to a 486 DX4-100, or in the version manufactured later, it allowed you to convert your Pentium 75 to Pentium 90 and even 100.
These Overdrives were made for the 80486 models, also for the later Pentiums, and some versions were even made for the Pentium II.
