Determinism. Unless you run your software simulator bare-metal - which

wait until the next virtual time tick, that is always a moving ratio or
opportunity for a context switch right at the threshold. I might want to
emulate a vintage i7 on an i19 one day.
You might start with a CDC STAR-100 and then graduate to the i7.
Does a STAR-100 emulator (software, I'm not even going to broach the
subject of hardware) even exist?
