Well, doing THAT workload, which is very CPU-bound, yes. BUT the mac was 
not idle, I was using it at the same time (anyway, SIMH eat almost an 
entire 2.4 core).

I was using the internal drive of the MacBook (SATA, 160 GB), and the 
VAX was working with a RF72 (DSSI) as system disk, but the compilation 
was done over a RZ26 (SCSI). OTOH the 4000-200 has just 40 MB of main 
memory, while the SIMH is configured with 128MB.


This is the accounting record for the compile in the 4000-200:

As you can see, I did the compilation in batch on the VAX, but did it 
interactively on the mac. So both records are not comparable "per se" (I 
did a lot more things on my interactive session, hence the difference in 
the number of images executed). If you want, I can't repeat the compile 
in batch in the mac so you'll have a set of comparable numbers.
