Not quite right but close!  The display enhancer will AUTOMATICALLY
detect the Productivity modes and bypass them to the monitor connected
to the 31Khz video port.  The user must manually toggle the bypass
switch on the back of the A3000 to do the same thing when in the
Superhires modes.  No the display enhancer does not enhace or
de-interlace either the productivity-interlaced or superhires-interlace
modes because it would require twice as much video memory and add
GREATLY to the cost of the machine.  Also, when you are in these modes
you do releize that you have only four colors to chose from and your
system bandwidth (DMA, etc.) is greatly increased - so I prefer to not
use these modes.
