I should've written that it was when film was the only real option unless 
you had money. I'd guess it was around 1998.

There are three issues with that:

One, I don't really trust x86, considering the Intel Management Engine and 
AMD PSP aren't openly documented, so I prefer to run important services on 

Two, emulation isn't perfect and there are occasionally edge cases which 
occur because of things that are ever so slightly off because of FPU 
accuracy or things like that.

Three, emulation is often not as fast as real hardware. A VAXstation 
4000/90a is about as fast as SIMH running VAX on a really fast x86, and 
m68k emulation is often slower than on a real m68060 because BSD requires 
an MMU, and that means that JIT can't be used.

Anyone? :D
