I have a VAXStation 3100 which is similar. I am told they are slow but usable.
Thanks,
Bryan

  Yes. Jerome he is right, he ist not intrrested in
your great numbers
 since hi want to emulate not a PDP11, but a VAX. 
 Actually, I found those numbers Jerome provided quite interesting. It wasn't
 me that asked about the speed of an emulator... but I'm sure the person
 asking got some datapoints. Thanks Jerome!
 I do have a Microvax 3100-40. I remember that I powered it up once when I
 got it, and it's been sitting on a shelf ever since (probably 10 years). I'm
 not familiar with those type of machines, is that fast enough to play around
 with?
