Microcode inside the Intel 8087 floating-point chip: register exchange (righto.com)

Author here if anyone has questions about the 8087's microcode...

Oooh... nothing quite as fun as a righto.com link popping up on a rainy Saturday afternoon with the kids napping...

There goes my next hour or two.

I must say: this, along with its other accompanying articles, provides wealth of information. Such a treasure. Thank you!
