When I was with AT&T, I used a 5620 Dot Mapped Display terminal for troff
previews.  I would pull down a full screen window and fire up the previewer.
Each time a new font was required, things stopped for a while for the font
to be downloaded into the DMD.  After a font was downloaded, the screen
preview went pretty fast.  Since the DMD is a multi-window device, I could
leave the preview program sitting in the "bottom" window when I wasn't
actively using it, and could do other work in other windows while the
previewer was crunching along.

I don't know what the current status of the DMD is.  There was talk about
a new line of terminals, including a new DMD based on the MC68000 family.
(The 5620 DMD is based on whe WE32000 family.)  I saw the first member or
two of the new family (which I believe have now been announced), but never
saw the new DMD.
