You are off by a year. October 2, 2000 SimNow!, the x86-64 simulator, has been released. x86-64.org

T G PRTNDER, the emulator is just for program debug and I'm sure did not simulate instruction timings. It probably ran at least 1000x slower than the real thing.

Well, it might have tried to simulate instruction timings, but whatever numbers it used were just guesstimates of the Clawhammer chip, since it was released so long ago, and instruction parallellism and timing is extremely difficult to predict even when you have silicon.
