More than 30.

I don't really know the performance penalty of emulators. AIUI a lot of 
the performance improvement of modern computers is due to software, 
working with pipelines, predictive branching, etc. Processor clock is 
only about 1000 times faster.

I first learnt of RISC when I was given a DECstation 3100 (Mips/Ultrix 
not a VAXStation) to work on. Circa 1991. Much faster than VMS, but 
already losing the battle to the PC.
