On the other hand, though... I'm moving to an apartment soon that is  
much smaller and is on the second floor... it has elevators, though.

The problem I am faced with, however, is my AS/400 and VAX 6000 are  
both 700 lbs each.  The VAX does that in 30" square.  According to  
standard floor loading for residential buildings, the area the VAX  
takes up should have no more than 250 lbs. loaded on it.  If you use  
the 1.4 x loading factor for 40 psf, you get up to 350 lbs.  I  
calculated that I'd need some sheet of material 4.1 ft on a side to  
slide under the thing to safely house it in the apartment.  Are there  
such sheets commonly available for this kind of purpose or should I  
use just 3/4" plywood?  Has anyone taken the batteries out of an AS/ 
400 and bypassed them?... that would take a lot of the weight out of  
that thing... which is about 2 ft by 3.5 ft.

I've never had a place yet where I had to elevate those boxes.
