[Coco] The New Hires Interface

[John Kowalski]

That would be about 32000 points, but the extended scanning is not
linear and not continuous between two normal DAC points, so extra
precision is used to mathematically try to map the reading to it's
actual position.  Then that result is scaled down to a useful range.

So it's not going to get single point readings (16384, 16385,
16486...etc...) at 15 bits.  Different ranges might skip by smallish
jumps, others by larger jumps.   It can detect higher precision in
some areas but only lower in others..  Overall, it works well when
scaled down to 320 coordinates.  It wouldn't work as well at 1024 or
greater output.
