Up for sale is an original Intel 80386DX-25 processor and matching Intel 80387DX-25 math coprocessor.Both came out of my personal collection of computer parts accumulated over 30+ years working in IT.These have been sitting in storage for decades. The last time I had a working 386 motherboard was somewhere around 1995, so testing them isn’t exactly an option today.Included:* Intel A80386DX-25 IV processor (SX133)
* Intel A80387DX-25 math coprocessor (SX106)Both are 25MHz and were designed to work together in compatible 386 systems.The chips appear to be in good physical condition. Please review the actual photographs, including the video of the pins.These are untested. I have no reason to believe they’re defective, but after 30 years in storage, I’m certainly not going to guarantee they work.You will receive the exact two chips pictured.If you’re restoring an old 386, here’s your chance to give these two relics something more productive to do than occupy space in my parts drawer.
