Zooming in on the microcode storage ROM, you can see the individual transistors, the pinkish blobs. The 8087 is very unusual, using four transistor sizes, giving it double density: 2 bits per transistor. The Opcode Collective examined all 13184 transistors, revealing the 0s and 1s of the microcode.

@kenshirriff@oldbytes.space Opcode Collective would be a great name for a band or a world class design group 🙂🤷♂️
