I'm incredibly pleased to announce that the microcode for the Intel 80386 has been decoded.

It was a group effort by a bunch of talented people to extract and correct the physical bits, but the major work of decoding them was done by reenigne - you may know him from such incredible PC demos as 8088 MPH and Area 5150, as well as being the person who decoded the 8088 microcode previously.

Please, check out his writeup.
