The Intel Pentium Overdrive CPU for 486 Systems

Back in 1995, Intel released a very special upgrade processor for owners of 486 systems. Despite having a very different architecture and external data bus, the Pentium Overdrive was able to drop right into an existing 486 system and provide next-gen performance. Was it a worth-while upgrade? Or was this heavily modified Pentium processor held back by the aging 486 platform? In today’s video I’ll be restoring a badly neglected 83MHz Pentium Overdrive and will try to answer that very question. If you'd like to support the channel, you can check out my Patreon page.
