The Intel 8087 was a floating-point coprocessor designed to be paired with either the 8088 or 8086 CPUs.

Help us extract the 8087 microcode ROM! This may one day lead to cycle-accurate emulation of the 8087.

The 8087 microcode ROM is unique in that it has quad-level cells, utilizing 3 different sizes of transistor. A convolutional neural network was trained to identify each transistor size, but now I need to verify the results.

I hope the legend at the lower-left will be self explanatory, and the pattern is pretty clear as the vast majority of bits are correct - we're just looking for errors. If you spot one, right click on where you see the problem and click the report link to automatically open a github issue.
