The Intel 8086 microprocessor was introduced 42 years ago today, so I made a high-res die photo. The 10-kilobit microcode ROM is visible in the lower-right corner. The 8086 started the x86 architecture that still dominates computing. The original IBM PC used the related 8088 chip pic.twitter.com/H5pkotbOnQ

The first photo is 4K×4K, so you should be able to zoom in. But I've attached some detail photos of that section, which I think is the data path and registers. Let me know if there's anything specific you want to see. pic.twitter.com/4wKkrHDS83
