Please try this:-
.sp 0.5i
This is text at \n[.ps] millipoints.
.sp 0.5i
.\" \D't -1'\D'l 1i 1i'\D't 0'\D'l -1i 1i'\D't 6000'\D'l 0 -1i'
\D'l 1i 1i'\s'.01p'\D'l -1i 1i'\s'150p'\D'l 0 -1i'\s'10p'
Drawing position ends up here.
I've removed the final ".sp 0.5i" so I can see where the drawing position
really ends. Also I don't understand why that ".sp 0.5i" moves _up_ the page
rather than down.
When you run this you should see something almost identical to your example,
but there are no \D't nnn' instructions at all. The reason it is not identical
is because you can't specify the minimal line width (your mode b!) using mode
1 because \s'0' means something else, so we still only have two separate ways
of setting the linewidth, one of which allows you to use zero as a width to
request the minimal width.
