Yes, I think I was wrong and they had to make some (minor, but
manual) hardware modifications. Plus they also developed a different field 
map which Steve R. posted to the list a while ago. So the ET version is
basically a customized, low-volume product.

I have gotten info on the (inexpensive) SPX controllers that "look like"
the DCP controllers we would need from Jeff @ Alltrax. It turns out these
were DCP controllers that had a problem with a bad component in the field
control circuit and thus were converted by Alltrax to standard controllers 
for series wound or PM motors.
