40Mhz VLB was usually doable, although not always reliable. This is 
especially true if you wanted to run two VLB boards at the same time. 
(i.e. video and disk controller) A friend was able to run a 50Mhz 
processor/VLB video card with generally good success. Finding the right 
video card took some doing, but DOOM was worth it. :)
