Conditions in the Intel 8087 floating-point chip's microcode

Author here if anyone has questions...

Until I read this I did not know that 1970s microprocessors had register renaming. Feel a little cheated, thinking for all those years that they were actually moving the bits.

super cool! i wonder how difficult it would be to recreate the entire chip at logic gate level in, say, VHDL or Verilog
