That VTTEST page have a couple of slightly incorrect bits of 
information, and the soft scrolling is a purely visual effect. The 
scrolling regions as such is also something that needs testing, but the 
soft scrolling part is yet another step on top of that.

So while VTTEST (in any version) would be a fun test, I would expect 
VTTEST should not be able to spot any errors if you are running the 
original VT100 firmware, as that is by definition doing the correct things.

But correct emulation of the hardware is yet again a different topic.
